Given the equations x + y = 20 and x - y = 8, which values of x and y satisfy both equations?
x = 11 and y = 9
O x= 9 and y = 11
X = 14 and y = 6
O x = 6 and y = 14

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
