11. Distributive Property: If 3(x + 7) = 30, then = 30. 12. The formula for the surface area of a rectangular prism is given by the equation A = 2lw + 2lh + 2hw, where l is the length, w is the width, and h is the height. Solve the formula for w and justify each step. Then find the width of the prism if the total surface area is 52 square inches, the length is 2 inches, and the height is 4 inches. 13. In the diagram, AB = 3 and BC = 5. Find the perimeter of the hexagon. Justify your answer using the properties of equality. ven C 十 4 and 3 opler m22 180 A
