Final Jeopardy Question x + 5 2x x – 4 x – 4 x x 2x x + 5 The perimeters of these rectangles are equal. Write an equation and solve for x. Answer

Final Jeopardy Question x + 5 2x x – 4 x – 4 x x 2x x + 5 The perimeters of these rectangles are the same. Write an equation and solve for x. Perimeter of left rectangle Perimeter of right rectangle P = x + x + 5 + x + x + 5 P = x – 4 + 2x + x – 4 + 2x = 4x + 10 = 6x – 8 Since the perimeters are the same, set them equal to each other 10 = 2x – 8 4x + 10 = 6x – 8 + 8 + 8 – 4x – 4x Board 18 = 2x 10 = 2x – 8 x = 9 2 2
