Question

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?

Answer 1

Answer: 6s+8

Explanation:

just did the assignment

Answer 2

1) 6s + 8

2) 50

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
