Step-by-step explanation:

Step 1:  Convert centimeter to millimeters

1 centimeter = 10 millimeters

29 * 10 = 290 millimeters

 290 millimeters

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
