Step-by-step explanation:

AB=DC

-x+6 = 3x-14

4x= 20

x= 5

AB=1

DC=1

f

step-by-step explanation:

f

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
