Match the circle equations in general form with their corresponding equations in standard form.

Tiles

x2 + y2 - 4x + 12y - 20 = 0

(x - 6) 2 + (y - 4) 2 = 56

x2 + y2 + 6x - 8y - 10 = 0

(x - 2) 2 + (y + 6) 2 = 60

3x2 + 3y2 + 12x + 18y - 15 = 0

(x + 2) 2 + (y + 3) 2 = 18

5x2 + 5y2 - 10x + 20y - 30 = 0

(x + 1) 2 + (y - 6) 2 = 46

2x2 + 2y2 - 24x - 16y - 8 = 0
