Consider a circle whose equation is x squared plus y squared minus 2 x minus 8 is equal to 0 Which statements are true? Choose three correct answers.

Complete the square in x: x² − 2x = (x − 1)² − 1. The equation becomes (x − 1)² + y² = 9, so the center is (1, 0) and the radius is 3. Thus, the radius is 3 units (B), the center lies on the x-axis (C), and the radius matches the circle x² + y² = 9 (D).
