Given
f(x) = 3x + 10 and g(x) = x + 2, find f (g(5))

Step-by-step explanation:

x+2=0

x=-2

f(-2)=3(-2)+10

=+5

I think this is what u want

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
