The accompanying Venn diagram shows the number of elements in region V. Use the given cardinalities to determine the number of elements in each of the other seven regions.
n(U) = 44, n(A) = 23, n(B) = 23,
n(C) = 18, n(AB) = 11,
n(ANC) = 8, n(BNC) = 13

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

Use composition to determine if (x) or h(x) is the inverse of f(x) for the limited domain x2-1.
