A=9 inches, b=12 inches, c=, is the hypotenuse known or unknown?

Unknown. C is the hypotenuse, but this problem is solvable.

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4

The answer is budget i believe. hope this but it’s self explanatory.
