A triangle has side lengths of (4h + 2k) centimeters, (9h + 4m) centimeters, and (2m - k) centimeters. Write an expression represents the perimeter, in centimeters, of the triangle. I will mark brainliest!

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
