Step-by-step explanation:
find the value of f(-4) first
f(-4) = (-4)^2 - 7 ➡ 9 use this to find g(f(-4))
g(9) = 5 - 9^2 ➡ -76

Answer:
x = 8
y = 4sqrt(3)
Step-by-step explanation:
Your knowledge of special triangles tells you the side ratios of a 30°-60°-90° right triangle are ...
1 : √3 : 2 = 4 : y : x
Multiplying the reduced ratios by 4 gives ...
4 : y : x = 4 : 4√3 : 8
That is, ...
x = 8
y = 4√3
