34.0, 33.2, 37.0, 29.4, 23.6, 25.9

In trapezoid bath, ah=19.7 and et=16.1. identify be.

25 ! the line of best fit is h = 5a + 86. predict the height at age 16.

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
