Answer:
1:-3, 1:2
Step-by-step explanation:
I believe the answer is C but don’t take my word on it
The P is 16x^2 -12 and Perimeter is the distance around the edge of a shape. So you divide your equation by 4 and the answer you get is 4x^2 - 3
11- \frac{1}{2} y=3+6x
Taking y to the other side;
11-3-6x= \frac{1}{2} y
8-6x= \frac{1}{2}y
Multiply each side by 2
16-12x=y
y=16-12x
