A rectangle has a length of 3x + 1 units and a width of 2x + 7 units. Select each algebraic expression that could represent the perimeter of the rectangle. (Make sure to select 2 or more equations!)

• 3x + 1 + 2x + 7

• 6x + 2 + 4x + 14

• 2(3x + 1) + 2(2x + 7)

• (3x + 1)(2x + 7)

• 3x + 1 + 3x + 1 + 2x + 7 + 2x + 7
