What does best approximates of 35,000,000 x 9 mean?

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

4+4+2x

or

2x+8

step-by-step explanation:

3xy cannot be combined with the others

2x, -5x and x are like terms
