Rewrite the equation in standard form. Find the center and radius of the circle.x2 + y2 + 12x - 8y - 183 = 0
A. (x - 12)2 + (y + 8)2 = 25
center (12, -8), r = 5
B. (x + 12)2 + (y - 8)2 = 25
center (12, -8), r = 5
C. (x + 12)2 + (y - 8)2 = 25
center (-12, 8), r = 5
D. (x - 12)2 + (y + 8)2 = 25
center (-12, 8), r = 5
