Figure klmn and figure pqrs, shown below, are similar figures.
if kn = 3 cm, mn = 7 cm, rs = 14 cm, and ps = 6 cm, what is the scale factor of figure pqrs to figure klmn?

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
