write a recursive formula for the arithmetic sequence below. what is the value of the 8th term? 1, 5, 9, 13, . . a. a (n) = a(n - 1) - 4; -27 b. a (n) = 4a(n - 1); 29 c. a (n) = a(n - 1) + 4; 29 d. a (n) = -4a(n - 1); -27

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
