Got it right on the practice :)
Answer:
D. x = -5
Step-by-step explanation:
The square root function is only defined for non-negative arguments. For the function ...

this means we must have ...
x +4 ≥ 0
x ≥ -4 . . . . . . subtract 4 from both sides
All of the numbers on your answer choice list are more than -4 except -5.
x = -5 is not in the domain of g(x)
Well, you can do
area=legnth times widht
perimiter=2(legnth+width)
then you just subsitute x for legnth and y for width then solve
area=xy
perimiter=2(x+y)
then graph and find the intersection to find the solution
