The sides of a triangle are represented by (3s - 1), (2s + 5), and (s + 4). 1.)Find the expression for the perimeter of the triangle.

2.) What will be the perimeter if s = 7?

1) 6s + 8

2) 50

Step-by-step explanation:

1)

To find the perimeter, add the lengths of the sides.

perimeter = 3s - 1 + 2s + 5 + s + 4

perimeter = 6s + 8

2)

Replace s with 7 in the perimeter expression.

perimeter = 6(7) + 8

perimeter = 42 + 8

perimeter = 50
