4. The figure shown was created by placing the vertices of a triangle within the circle. What is the area of the shaded region? Use 3.14 to approximate π, remember to answer using cm2. Show your work and don’t forget to add the units to your answer.

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
