Area of entire trapezoid = <span>((sum of the bases) ÷ 2) • height
Trapezoid Area = (51 / 2) * 26
</span><span>Trapezoid Area = 663
UN-shaded triangle area = .5 * base * height
</span><span>UN-shaded triangle area = .5 * 23 * 26
</span><span>UN-shaded triangle area = 299
SHADED Trapezoid Area = 663 -299
</span><span>SHADED Trapezoid Area = 364

4) -1/2(y-x)
Multiply -1/2 to y and x
-1/2y+ 1/2x
5) a(8+2b-6)
Multiply a to the equation in parentheses
8a+2ab-6a
Add like terms which are 8a and -6a
2ab+2a
6) -2.5(-3+4n+8)
Multiply-2.5 to the equation in the parentheses
7.5-10n-20
Add like terms which are 7.5 and -20
-10n-12.5
First of all, since all powers of x in this function are even, the entire function is even. Thus, using -x as input doesn't change the function. Thus, f(-x)=2x^2-4.
