Question

If the perimeter of the triangle is 95 inches, what is the length of each side? n, 3n+8, and 4n+7.

Answer 1

10, 38, 47

Explanation:

The perimeter is the sum of the side lengths:

95 = n +(3n +8) +(4n +7)

80 = 8n . . . . . . subtract 15

10 = n

3n+8 = 3(10) +8 = 38

4n+7 = 4(10) +7 = 47

The lengths of the sides of the triangle are 10, 38, 47.
