A quadrilateral has sides with lenghts: 2x, x+4, 2x-2, and 3x+1. Write an expression for the perimeter of the quadrilateral.

Question

2x, x+4, 2x-2, and 3x+1 

Write an expression.

Answer 1

The perimeter is simply the sum total of the lengths of the various sides. Therefore:

p = 2x + (x+4) + (2x-2) + (3x+1) = (2x+x+2x+3x) + (4-2+1) = 8x+3
