Question

the 3 sides of a triangle have lengths of (x+7) inches, (5x+6) inches, and (5x-3) inches. What is the length of the shortest side if the perimeter of the triangle is 43 inches

Answer 1

The length of the shortest side would be 10in because x = 3.
3 + 7 = 10
5 x 3 + 6 = 21
5 x 3 - 3 = 12

10 + 21 + 12 = 43

10<12<21

So 10 would be your answer :)
