Answer:
x = -3
Step-by-step explanation:
3x + 9 = 12x + 36 (rewrite)
3x - 12x + 9 = 36 ------> 3x - 12x = 36 - 9
3x - 12x = 36 - 9 (collect like terms)
-9x = 36 - 9 ( substract)
-9x = 27 (divide both sides for the answer)
-9 -9
x = -3
You can say that the center is an arbitrary point at (x0, y0)
The distance from each point to the center is the same
d^2 = (x-x0)^2 + (y-y0)^2
Plug in each point into this equation (plug into x and y) and you have a 3x3 system that you can solve for x0 y0 which is the center and d which is the radius. Then you have the equation by putting these constants into the above equation.

![\sqrt[n]{x^a}=x^{a/n}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5Ea%7D%3Dx%5E%7Ba%2Fn%7D)
Step-by-step explanation:
While the "law"
![\sqrt[n]{x^n}=x](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5En%7D%3Dx)
may seem more applicable, and may seem to be a special case of the law shown in the answer above, it is not true in general. For example, ...
