x = length of side a

2x - 1 = length of side c {side c is one less than twice side a}

2x + 3 = length of side b {side b is 4 more than c....added 4 onto 2x - 1}

x + 2x - 1 + 2x + 3 = Perimeter {added all sides together}

**Perimeter = 5x + 2** {combined like terms}

In terms of side a, it is "2 more than five times the length of side a", since side a was x.
