G(x)= -x^2 as when you square a negative it has the same result as a positive
Answer:

Step-by-step explanation:
So when you're solving for y you want to get y by it self meaning there should be nothing with y, including any coefficients. The first step is to usually move any terms to the other side and then divide by the coefficient of y so y "technically doesn't" have a coefficient, while it does, but that coefficient 1, so it doesn't really mean much.
Subtract x from both sides

Divide both sides by 6

Put all the x together and add the whole number. This is what U will get
Answer:
113 (d)
Step-by-step explanation:
Since the room is square-shaped, you square root the area (12,769) to find the length of each wall. You will get the answer 113. To check this answer multiply 113 by 113 and make sure you get the correct area; it works, so you know the answer is D.
That is all correctly answer good job
