Match the circle equations in general form with their corresponding equations in standard form. 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 x2 + y2 + 2x ? 12y ? 9 = 0
