Match the circle equations in general form with their corresponding equations in standard form.
x2 + y2 β 4x + 12y β 20 = 0
(x β 6)2 + (y β 4)2 = 56
x2 + y2 + 6x β 8y β 10 = 0
(x β 2)2 + (y + 6)2 = 60
3x2 + 3y2 + 12x + 18y β 15 = 0
(x + 2)2 + (y + 3)2 = 18
5x2 + 5y2 β 10x + 20y β 30 = 0
(x + 1)2 + (y β 6)2 = 46
2x2 + 2y2 β 24x β 16y β 8 = 0
x2 + y2 + 2x β 12y β 9 = 0
