Two vertices of a right triangle have coordinates (20, 15) and (20, 27) . the segment that connects these points is a leg of the triangle.
which coordinate pair for the third vertex would create a right triangle?
(7, 27)
(20, 32)
(27, 20)
(20, 20)

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
