Q: If you are working with a negative fraction, it will have a minus sign in front of it. It is good practice to always put parentheses around a negative number so you know that the "" sign is referring to the number and not telling you to subtract two numbers. For example: (2/4) Square the fraction as you would normally by multiplying the numerator by itself and then multiplying the denominator by itself. Alternatively, you can simply multiply the fraction by itself. For example: (2/4)2 = (2/4) x (2/4) When a minus sign is present, the entire fraction is negative. When you square the fraction, you are multiplying two negative numbers together. Whenever two negative numbers are multiplied together, they make a positive number. For example: (-2) x (-8) = (+16) After you have squared the fraction, you will have multiplied two negative numbers together. This means that the squared fraction will be positive. Be sure to write your final answer without the negative sign. Continuing the example, the resulting fraction will be a positive number. (2/4) x (2/4) = (+4/16) Generally, the convention is to drop the "+" sign for positive numbers. The final step when doing any calculations with a fraction is to reduce it. Improper fractions must first be simplified into mixed numbers and then reduced. For example: (4/16) has a common factor of four. Divide the fraction through by 4: 4/4 = 1, 16/4= 4 Rewrite simplified fraction: (1/4)
A: Recognize the negative sign in front of the fraction. Multiply the fraction by itself. Understand that two negative numbers multiply to make a positive number. Remove the negative sign after squaring. Reduce the fraction to its simplest form.

Q: Before you begin, contact your water purveyor or municipal water department to ask about laws, codes, and permits related to drip irrigation systems. Each area and water purveyor may have its own requirements, and some require a licensed irrigator and/or backflow tester to be present during the installation. These precautions ensure a safe installation that will prevent contamination from your irrigation system into drinking water. If you plan on using the drip irrigation as a temporary system while your landscaping gets established, mention the expected time frame. The requirements may be lighter. In many areas, including some U.S. states, proceeding without the proper permits or supervision can lead to fines, a court appearance, or even jail time. Your drip emitters and tube diameter will determine the system's maximum GPH (gallons per hour). In order to meet your entire garden's water needs, you may need to divide your system into several zones. By installing a "zone control valve" in each zone, you can direct flow to one or two zones at a time. It's best to install each valve near the center of the zone, so it pushes water out at even pressure in all directions. If the drip system will be permanent, it's worth the cost of an electric valve that hooks up to an irrigation controller. Manual valves are tedious to operate and often mistakenly left operating for longer than intended. The equipment you buy should come with recommended maximum tube length and GPH. You can also calculate this yourself using hydraulic flow calculations.
A: Check legal requirements. Divide your garden into watering zones.

Q: Labor will need to be induced in a preeclampsia pregnancy past 37 weeks of gestation. At this point your baby should be fully developed and ready to live outside the womb. Delivering at this time should alleviate the preeclampsia and may prevent other complications. If the doctor induces delivery, he or she may: Do a membrane sweep. During this procedure the doctor uses a finger to separate the amniotic sac from the cervix. It will stimulate your body to release hormones which may start labor. It may be a little uncomfortable or cause some bleeding. Insert a medication into your vagina. This may be in the form of a tablet or gel. This will help your cervix to soften. It may take up to 24 hours for labor to start. If this does not work you may be given another dose or an intravenous hormone drip. Administer anticonvulsant medications during labor if necessary. For example, if you have severe preeclampsia, then you may receive magnesium sulfate during labor to help prevent seizures. However, magnesium sulfate is not necessary if your preeclampsia is mild. If your symptoms are very severe, it may be necessary for you to have an emergency C-section (Cesarean delivery). This procedure requires that the doctor make an incision through your abdomen wall and into the uterus so that they baby can be removed from the uterus without being delivered vaginally. This would be done if it is too dangerous for you or the baby to continue the pregnancy. If necessary, the doctors may give you magnesium sulfate to keep you from having seizures during the procedure. Medications would combat the symptoms and may enable the pregnancy to continue for a bit longer. This would give the baby more time to mature in the womb. If you do take medications, talk to your doctor about whether they may cause harm to your baby. Possible medications include: Blood pressure medications. If your blood pressure is borderline, 140/90 m Hg, you may not be prescribed medications. But if it is dangerous or you or the baby, the doctor may feel it is necessary to control your blood pressure and reduce your risk of a stroke. The medication labetalol is licensed to be used in women with high blood pressure. Other medications that are not licensed for pregnant women but sometimes prescribed include nifedipine or methyldopa. If you have been prescribed either of these, be sure to discuss the risks to you and your baby with your doctor. Corticosteroids. These medications can be used to stimulate lung maturation in your baby in 1-2 days. This may be necessary if your baby will have to be born premature. In addition, these medications may be used to reduce symptoms due to problems with your liver or platelets. Anticonvulsant medications. These medications would be prescribed if your risk of having a seizure is high or if you have already had seizures.
A: Talk to your doctor about inducing delivery if you are at 37 weeks. Have a Cesarean delivery if necessary. Prolong the pregnancy with medications if necessary.

Q: Keep the magazines you collect or want to reread at a later time. Set aside magazines with helpful information to come back to later. Then, recycle any magazines you no longer need. This will eliminate extra clutter from your home so your magazines will be organized and easy to access! If you prefer to keep things organized in alphabetical order, then arrange your issues by title so the magazines that start with "A" are on the left side, and the magazines starting with "Z" are on the right. Then, place your magazines in their appropriate place in between. If you have many magazines on the same subject, such as scrapbooking, cooking, or bodybuilding, then organize them categorically. For example, if you are looking for a new recipe for dinner, you can easily go to the "Cooking" section and locate an issue. File holders are small boxes or racks that allow you to display files, or in the case, magazines, vertically. After you choose your organizational method, put your magazines into the holders accordingly. You can fit 8-12 magazines in a standard file holder, depending on the thickness of your copies. For example, if you have many craft magazines and you want to organize them thematically, put all your craft magazines in the same holder. After you place all of your magazines in their respective holders, you should label them so you can easily locate individual issues. Write the name of the magazine, and include the issue numbers if you'd like. You can write directly onto your magazine holders with a permanent marker, or use sticker labels and adhere them to the front of your holders. If you want to use a label maker, turn on your machine and type in the title of your label, such as "Animals." Then press "Print" to create your label. Peel off the backing and stick your label onto your file holder. You can situate the file holders anywhere you like. Keeping them on a bookcase is a great way to keep them organized and easily accessible. You could also store them in closet, on shelves, or even in a storage area like a basement or attic.
A:
Sort through your magazines and decide which to keep, recycle, or clip. Arrange your magazines alphabetically to easily locate issues. Organize your magazines based on theme to group hobbies together. Place your magazines into file holders. Label each file holder with a marker, sticker, or a label maker. Line up the file holders on a bookcase or in a closet.
