Two sides of a triangle have lengths 11 and 18. write an inequality to represent the possible lengths for the third side, x.

Step-by-step explanation:

Given: Two sides of a triangle have lengths 11 and 18.

The third side is represented by x.

So by triangle inequality, we have the following inequality:

Also, the difference between the lengths of any two sides of a triangle is less than the length of the third side.

Thus, the inequality to describe the possible side length for the third side is

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

7.3
