Evaluate x + 12 when x=5

17

Step-by-step explanation:

5+12

the answer is 18.

Step-by-step explanation:

x + 12 when x = 5.

so x = 5.

5 + 12 = 18

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
