The circle below is centered at the point (2, -1) and has a radius of length 3. What is its equation?

O A. (x + 2)2 + (- 1)2 = 32
O B. (x - 1)2 + (y + 2)2 = 9
O C. (x - 2)2 + (y + 1)2 = 32
O D. (x + 1)2 + (Y - 2)2 = 9

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
