Answer:
2
Step-by-step explanation:
Add all of the interior angles to 1260. Then you simplify for x. After that you plug in what you found for X in the E expression.
X=3.5 add 10 and divide by 8
(f-g) (x) means to subtract g(x) from f(x)
F(x) = 2x^2 +3
g(x) = x^2
This becomes:
2x^2 + 3 - x^2 = x^2 +3
