Which equation is correct? 75 × 4 = 70 × 4 + 5 × 4

75 × 4 = 70 + 5 × 4

75 × 4 = 70 × 4 + 5

75 × 4 = 700 × 4 + 5 × 4

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
