Answer:

AC=7.5 cm

CB=10.5cm

Step-by-step explanation:

Since we don't know the distance from C to B, we can label it as x. Our equation will be x+(x-3)=18. Simplify that so it is 2x-3=18. Add 3 to both sides and get 2x=21. x=10.5 So AC=7.5 cm and CB is 10.5 cm

First, find the value of g(x) at x=4: it's 3.

Next, use this result, 3, as the input to f(x): f(3) = 1

So f(g(4)) = 1.
