7y y 104 Find the volumes of boxes I, II, and III in the figure to establish the difference of two cubes formula for the special case x Ͼ y. 4 Fractional Expressions (a) Determine the basal energy requirements first for a 25-year-old female weighing 59 kilograms who is 163 centimeters tall and then for a 55-year-old male weighing 75 kilograms who is 178 centimeters tall. (b) Discuss why, in both formulas, the coefficient for y is negative but the other coefficients are positive. A fractional expression is a quotient of two algebraic expressions.

If the elements of a set S have a certain property, we sometimes write S ϭ ͕x: ͖ and state the property describing the variable x in the space after the colon. The expression involving the braces and colon is read “the set of all x such that . . ,” where we complete the phrase by stating the desired property. ” For finite sets, we sometimes list all the elements of the set within braces. Thus, if the set T consists of the first five positive integers, we may write T ϭ ͕1, 2, 3, 4, 5͖. When we describe sets in this way, the order used in listing the elements is irrelevant, so we could also write T ϭ ͕1, 3, 2, 4, 5͖, T ϭ ͕4, 3, 2, 5, 1͖, and so on.
