Let U = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,1 5,16,17,18). A = (1,3,4,5,6,13,14,15,16,18), B = (1,5,6,7,9,11,12,13,14,16,17), and C={1,2,3,4,7,8,10,11,16,18) Find (A-B) n (C-B)

Name the quadrilaterals that have four equal sides.

Which of the following is true about the graph of f(x)=7^x. select all that apply. a= it intercepts the x axis b=it intercepts both axis c=it intercepts neither d=it intercepts the y axis

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
