Answer:
x = 4 in
Step-by-step explanation:
Given a tangent and a secant to the circle from an external point, then
The square of the tangent is equal to the product of the secant's external part and the entire secant, that is
x² = 4(4 + 8) = 4 × 12 = 48 ( take the square root of both sides )
x = =
=
×
= 4
← exact value

The first thing we are going to do to find (g°f)(3), is find (g°f)(x). To do that, we are going to evaluate g(x) at f(x):
(g°f)(x)=
Now, we can evaluate (g°f) at 3:
We can conclude that the correct answer is c. 49
