Finding F'(5) from F(x) = f(g(x))

[TsAmE]

Homework Statement

If F(x) = f(g(x)), where f(-2) = 8, f'(-2) = 4, f'(5) = 3, g(5) = -2, and g'(5) = 6, find F'(5).

Homework Equations

F'(x) = f'(g(x)) * g'(x) - Chain Rule

The Attempt at a Solution

F'(x) = f'(g(x)) * g'(x)
F'(5) = f'(g(5)) * g'(5)
F'(5) = f'(-2) * 6
F'(5) = 8 * 6
F'(5) = 48

The correct answer is 24 which doesn't make sense.
