Which choice correctly identifies the center and the radius of the circle expressed by the equation x² + y2 + 10x - 2y - 10 = 0?
1) C: (5, -1)r=6
2) C: (5, -1) r= square root 10
3) C: (-5, 1) r= 6
4) C: (-5, 1) r= square root 10

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
