What are the values of x, y, and z?
x = 17, y = 15, and z = 13
x = 13, y = 15, and z = 17
x = 15, y = 13, and z = 17
x = 13, y = 17, and z = 15

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

The suare root of 9x plus 7 plus the square rot of 2x equall to 7
