Which expression gives the distance between the points (-3, 4) and (6,-2)?
O A. (-3 - 4) * +(6+2)
O B. (-3-6)* + (4 +2)
O c. +(-3-6)* +(4+2) ?
O D. (-3 - 4) * +(6+2)

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
