The answer will be 8!
When you add them together you will get the equation -x^2 -2x + 8
When you plug in negative 2 it will be -4 + 4 + 8. Which will equal 8!

Answer:

8

Step-by-step explanation:

When we have something like (g+f)(x), we have to take g(x) and f(x) and then add them up. Let's start by finding g(-2) and f(-2):

[tex]g(x)=5-x^2\\g(-2)=5-(-2)^2=5-4=1\\\\f(x)=-2x+3\\f(-2)=-2(-2)+3=4+3=7[/tex]

Now, we just add them up to get our answer: 7 + 1 = 8
