Name: R Number: Forr 7. Complete the square and write the equation in standard form. Then give the center and radius of the circle. x² + y² + 18x - 10y = -97 A. (x - 5)² + (y + 9) ² = 9 Center: (5,-9), radius: 3 B. (x - 5)² + (v + 9)² = 9 Center: (-5,9), radius: 9 C. (x + 9)² + (x - 5)² = 9 2 Center: (-9,5), radius: (x + 9)² + (x - 5)² = 9 Center: (9,-5), radius: 9
