Find g(-2) + h(4) if g(x)= 5-2x and h(x) = - x2 pls help

-7

Step-by-step explanation:

g(x)= 5-2x and h(x) = - x^2

g(-2) + h(4)

First find g(-2)

g(-2) = 5 -2(-2) = 5 +4 = 9

Then find h(4) = - 4^2 = -16

g(-2) + h(4) = 9-16 = -7

i just took the test, the correct answer is .. 31.5 in.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
