Q: This will help you put the replacement wiper back in the correct position once the current wiper has been removed. Bar soap, wax, or another easy to remove mark will work fine. This may require that the hood be opened. Most designs have a plastic or metal dust cap that covers the drive post and hex nut that hold the wiper arm in place. With this dust cap removed, you will have the access you need to remove the nut. Now that the dust cap is removed and you can analyze the hex nut that holds the wiper arm onto the drive post you should choose a socket that fits it. Place the socket on the ratchet or, if needed, on an extension that is attached to the ratchet. Ratchets are designed to twist nuts and bolts on and off. You want to be sure you are set to spin in a counter clockwise direction. This will loosen the nut. Using your ratchet to remove this nut will allow you to remove the wiper arm from the vehicle. Place the socket and ratchet fully over the hex nut and hold in place with one hand while Stabilizing the wiper arm by firmly gripping it with the other hand. This will prevent the linkage from exceeding the designed range of motion when twisting the ratchet. Twist the ratchet to spin the nut counter clockwise one half to one full turn. Once the hex nut is loosened, release your grip of the wiper arm and remove the socket and ratchet from the hex nut. Spin the hex nut completely off by hand and set aside for reuse. Lift the wiper blade up from the windshield with one hand and hold the point of attachment with the other. Gently "rock" the wiper blade back and forth while lifting with both hands and remove from the drive post.
A: Mark where the windshield wiper blade rests. Follow the wiper arm away from the wiper blade to its base. Remove the dust cap at the base of wiper arm. Select a socket sized to fit the hex nut. Set the ratchet to allow it to loosen the nut. Remove the nut that fastens the windshield wiper arm to the drive post. Remove the entire wiper arm from the drive post.

Q: It will be impossible to solve the questions on your next test if you don't know what they are asking. Luckily, the terminology is not incredibly hard: Terms: A term is simply a part of the equation being added or subtracted. It can be a constant, variable, or both. For example, in 12 + 13x + 4x2, the terms are 12, 13x, and 4x2. Binomial: This is just a complicated way to say "an expression with two terms," like x+3 or x4 - 3x. Powers: this refers to an exponent on a term. For example, we could say that x2 is "x to the second power." Any question asking you to "Find the terms of two binomials (x+3)(x+2)," "find the product of two binomials," or "expand the two binomials" is asking you to multiply binomials. FOIL is a simple guide for multiplying two binomials. FOIL stands for the order you need to multiply the parts of the binomials together: F is for First, O is for Outer, I is for Inner, and L is for Last. The names refer to the order in which the terms are written. Let's say we are multiplying the binomials (x+2) and (x+5). The terms would be: First: x & x Outer: x & 5 Inner: 2 & x Last: 2 & 5 This is the "F" of FOIL. In our example, (x+2)(x+5), the first terms are "x" and "x." Multiply these together and jot down the answer: "x2." First Term: x * x = x2 These are two outermost "ends" in our problem. So, in our example (x+2)(x+5), they would be "x" and "5." Together they make "5x" Outer Term: x * 5 = 5x The two numbers closest to the center will be your inner term. For (x+2)(x+5), this means you multiply "2" and "x" to get "2x." Inner Term: 2 * x = 2x This does not mean the last two numbers, but rather the last number in each parentheses. So, for (x+2)(x+5), we multiply the "2" and the "5" to get "10." Last Term: 2 * 5 = 10 Combine the terms by adding them together to create a new, larger expression. From our previous example, we get the equation: x2 + 5x + 2x + 10 Like terms are parts of the equation that have the same variable and power. In our example, the terms 2x and 5x both share an x, and can be added together. No other terms are alike, so they stay put. Final Answer: (x+2)(x+5) = x2 + 7x + 10 Advanced Note: To learn how like terms work, remember the basics of multiplication. 3 * 5, for example, means that you are adding three fives together to get 15 (5 + 5 + 5). In our equation, we have 5 * x ( x + x + x + x + x) and 2 * x (x + x). If we add all the "x"s in the equation we get seven "x"s, or 7x. When a number is being subtracted, it is the same as adding a negative number. If you forget to keep the minus sign throughout your calculations you will end up with the wrong answer. Take the example (x+3)(x-2): First: x * x = x2 Outer: x * -2 = -2x Inner: 3 * x = 3x Last: 3 * -2 = -6 Add all terms together: x2 - 2x + 3x - 6 Simplify to final answer: x2 + x - 6
A: Understand math vocabulary and question types. Learn the acronym FOIL to remember the order of binomial multiplication. Multiply the FIRST part in each parentheses. Multiply the OUTER parts in each parentheses. Multiply the INNER parts in each parentheses. Multiply the LAST parts in each parentheses. Add all of the new terms together. Simplify like terms. Remember that subtracted numbers are negative.

Q: Frame construction is ISO Class 1. ISO Class 1 encompasses IBC Type VA and IBC Type VB. Regardless of whether the IBC classification is A (protected) or B (unprotected) the ISO Class is 1. Frame buildings are buildings with exterior walls, floors, and roofs with combustible construction or buildings with exterior walls of noncombustible or slow-burning construction with combustible floors and roofs. Frame buildings generally have roof, floor, and supports of combustible material, usually wood, and combustible interior walls. Two variations on frame construction don't change the construction class: Masonry veneer (brick veneer)- Masonry veneer is thin layers of brick, stone, or stucco, used for appearance purposes rather than structural support. Metal clad - A building with a metal exterior wall may not look like frame construction, but when the metal skin is attached to wood studs and joists, ISO classifies the building as frame. Other conditions that lead to classification as frame construction include: Metal walls or floors sheathed with combustible materials Metal floors or roofs with combustible insulation or ceiling material attached to the underside or within 18 inches (45.7cm) of horizontal supports Composite assemblies of noncombustible materials with combustible materials easy to erect and alter economical versatile performs well in Earthquake areas can move fire can spread rapidly highly damageable may become unstable in a fire may include enclosed spaces where fire can spread undetected
