Rewrite the equation in standard form. Find the center and radius of the circle.x2 + y2 + 4x + 10y + 29 = 36
A. (x + 2)2 + (y + 5)2 = 36 center (-2, -5), r = 36 B. (x + 5)2 + (y + 2)2 = 36 center (-5, -2), r = 6 C. (x + 2)2 + (y + 5)2 = 36 center (-2, -5), r = 6 D. (x - 2)2 + (y - 5)2 = 36 center (2, 5), r = 36
