Answer:

Explanation:

To find g(20) + h(7), we first need to evaluate the functions g(x) and h(x) at the given values.

Let's start with g(x) = |-3x + 16|. To find g(20), we substitute x = 20 into the function:

g(20) = |-3(20) + 16|

= |-60 + 16|

= |-44|

= 44

Next, let's evaluate h(x) = -x^2 + 8x for x = 7:

h(7) = -(7)^2 + 8(7)

= -49 + 56

= 7

Now, we can find g(20) + h(7) by adding the values we obtained:

g(20) + h(7) = 44 + 7

= 51

Therefore, g(20) + h(7) equals 51.
