Question

A triangle has two sides of length 13 and 8. What compound inequality describes

the possible lengths for the third side, x?
Write a compound inequality like 1

Answer 1

5 < x < 21

Explanation:

The shortest would be if the 8 leg folded back on the 13 leg

13 - 8 > 5

The logest would be if the 8 leg extended the 13 leg

13 + 8 < 21

Therefor

5 < x < 21
