Please! The number of cars sold in May (m) was 60 less than 4 times the number of cars sold in April (a). Which equation shows the relationship between m and a?
A: m = a - 60
B: m = 60 - 4a
C: m = a^4 - 60
D: m = 4a - 60

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
