Hello,
Center is (2,-11) and radius is 8
First subtract h from h to get - 2h
Then add 19 to both sides leaving you with
-2h = -32
Then divide by -2 on both sides
H = 16
You need to write the entire function: y = f(x) = 2x + 6.
Here the input quantity is x, and the output is y (or f(x)).
Since the area of a square is side squared, you can find the length of each side by finding the square root of the area, which is 5. Since there are four sides in a circle, just multiple 5 by 4 and your answer is 20 units.
