Answer
16
Explanation
Functions are:
g(x) = 2x and h(x) = x2 + 4
To evaluate g(-2) substitute x = -2 into the function.
2 • -2 = -4
To evaluate h(4) substitute x = 4 into the function.
4^2 + 4 = 20
Add the 2 functions
-4 + 20 = 16

You have defined x to be the smaller of two consecutive integers. Then the larger will be (x+1). The given relation is
... (x) + 3(x+1) = -5 . . . . the smaller plus 3 times the larger is -5
... 4x + 3 = -5 . . . . . . . .simplify
... 4x = -8 . . . . . . . . . . subtract 3
... x = -2 . . . . . . . . . . . divide by the coefficient of x
The smaller of the two integers is -2.
