Which pair of measurements are possible if they are congruent figures? 1. mZW=47º and m 2. mzx=940 and m - 79°
3. mW-47º and m 4. m2 X= 140° and m

Me because some of question i don’t understand

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
