What is the answer to this question 9785*86735

Figure abcd is a parallelogram. if point c lies on the line x = 2, what is the y-value of point c?

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

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9
