The area of a trapezoid is given by the formula a = (b 1 + b 2)h, where base b 1 is parallel to base b 2 and h is the height. solve the formula for b 2. show your work.

a

b

d

step-by-step explanation:

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
