find the missing length of the triangle

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

What is the measure of ac? 5 units 13 units 26 units 39 units 3x- 2b 6x + 9

Ab and bc are tangent to circle d. find x is ab = 3x + 8 and bc = 26. find x
