The length of the bottom of the triangle is x. Another side is 1 more than three times the length of the triangle. the last side is 2 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle.

The sides are x, 3x+1 and x+2

so perimeter = x+3x+1+ x+2 = 5x+3
