8.(5.5 in the ry-plane we want to go from a(0,0) to b(9,6) along the lines of the form z = i and y = j are integers with the shortest paths. let c(3,3 and d(4,3 (i, j (1) how many ways are there? (2) how many ways are there via d? (3) how many ways are there if the road from c to d is closed?

If eh = hg and hg=16, find the diameter of k

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
