Complete the square and write the equation in standard form. Then give the center and radius of the circle.x2 + y2 - 12x - 10y = -12
A. (x - 6)2 + (y - 5)2 = 49
(6, 5), r = 7
B. (x - 6)2 + (y - 5)2 = 49
(-6, -5), r = 49
C. (x - 5)2 + (y - 6)2 = 49
(5, 6), r = 7
D. (x - 5)2 + (y - 6)2 = 49
(-5, -6), r = 49
