Stiven received a new entertainment center for his bedroom. It holds his TV, VCR, stereo, CD player, and tapes. It sits on a pedestal base that is the shape of a trapezoid. The two bases of the trapezoid are 25 inches and 18 inches long, and the height is 14 inches. What is the area of the front of the base?

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

it is x=-4

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:
