Article: The 1 is always understood, and so is rarely written. However, when adding, writing the 1 can help you keep track of coefficients. A coefficient is the number in front of the radical sign. For example, write 5{\displaystyle {\sqrt {5}}} as 15{\displaystyle 1{\sqrt {5}}}. You can only add square roots that have the same radicand. The radicand is the number underneath the radical sign. For example, you can add the first three terms in the expression 25+125+5+7{\displaystyle 2{\sqrt {5}}+12{\sqrt {5}}+{\sqrt {5}}+{\sqrt {7}}}, because they all have the same radicand (5). Only add the coefficients for terms that have the same radicand. Do NOT add the radicands. For example, 25+125+15=155{\displaystyle 2{\sqrt {5}}+12{\sqrt {5}}+1{\sqrt {5}}=15{\sqrt {5}}}. These cannot be simplified any further, and cannot be added to any other terms. The result will be your final, simplified answer. For example, 155+7{\displaystyle 15{\sqrt {5}}+{\sqrt {7}}}.

Place a 1 in front of any square root that doesn't already have a coefficient. Check for square roots with the same radicand. Add the coefficients. Add any unlike radicands to the expression.
Article: Your accessories don't have to match the table exactly, but they should complement it. Try to stick with the same theme or type of materials when you choose your accessories. For example, if you have a rustic-looking table - made mostly from wood with an unfinished look - choose rustic accessories. These might include a vase made to look like a wooden branch or natural-looking flowers. If your table is made mostly from metal, consider choosing a few accessories that are also metal, but with a slightly different finish. You don't need to go out and buy new accessories and decorations for your table. Choose personal accessories that already match the theme or look you're aiming for. For example, if your favorite family photographs are in metal frames, use them to complement and decorate a metal end table. You can also stack up a few of your favorite books - just make sure you put them back after you read them so you don't lose your accessories! When you're choosing your accessories, keep in mind what you'll use the table for. If you're using the table to decorate your space, you can choose accessories that will take up most of the table. If you want the table to more functional, use fewer accessories. For example, if you're using an end table to flank a larger piece of furniture, you can use more accessories. If you're placing the end tables near a sofa or chair to hold glasses, cups, or something else, use fewer accessories. You don't want your end tables to look out of place in the rest of the room. Make sure that the table accessories match your other decor. For example, if your house has a country feel to it, white or wooden end tables that look slightly unfinished will go well with similarly rustic accessories. If your home is more modern, choose sleek end tables with simple accessories.

Decorate the table to complement its material. Include accessories with personal meaning. Consider what you'll use the table for. Match your table accessories to your other decor.
Article: Pilar cysts develop after puberty and have an autosomal dominant inheritance. This means that they occur in both sexes and if one parent carries the gene for a pilar cyst then it increases the risk that the children will experience these cysts. Seventy percent of people who get them will have multiple cysts over their lifetime. There is no known cause at this time for cysts that develop in the breast tissue. Doctors do not have a clear answer about the risk factors and prevention for Cystic acne but it is believed to be related to increasing hormonal levels in puberty and pregnancy and deep infections from hair follicles plugged by sebum (oil on the skin). Most cysts are not but some are. For instance, prevention for a pilonidal cyst includes wearing clothing that is not tight, maintaining normal weight limits, and getting up from a seated position every 30 minutes throughout the day. According to the American Academy of Dermatology, there is no effective means of preventing an epidermoid cyst from forming. However, there are groups of people who appear to be at greater risk for developing them: more men than women, acne sufferers, and people who spend a long time in the sun. People who have suffered hand injury are more likely to experience an epidermoid or ganglion cyst on the hand. Bartholin gland cysts can occur after injury to the area at the opening to the vagina. While most cysts are not preventable, you can lower your risks of getting the ones that are. Use oil-free skin products and avoiding excessive sun exposure. Shaving and waxing may also be responsible for cyst formation. Avoid excessive shaving and waxing in areas where you have already gotten cysts to prevent reformation or new cysts.
