Complete the square and write the equation in standard form. Then give the center and radius of the circle.x2 + y2 + 6x + 8y + 25 = 16
A. (x + 4)2 + (y + 3)2 = 16 (-4, -3), r = 4 B. (x + 3)2 + (y + 4)2 = 16 (3, 4), r = 16 C. (x + 4)2 + (y + 3)2 = 16 (4, 3), r = 16 D. (x + 3)2 + (y + 4)2 = 16 (-3, -4), r = 4
