Question

The two sides of a triangle have lengths 10 and 18. Which inequalities describe the values that possible lengths for the third side?

Answer 1

\[a) 8 \le x \le 28 or b) 8 < x < 28 c) 10 < x < 18 d) 10 \le x \le 18\]

Answer 2

those are our options

Answer 3

Let x equal the third side.
\[10 + 18 \ge x\]

Answer 4

0<x<10+18
(x can't be 0)

Answer 5

and it also can't be equal to 10+18, that would be a straight line

Answer 6

so It's not C?

Answer 7

This is my first time doing a problem like this, so I need a clear explanation

Answer 8

you can call it "c", if you want... "x" is used for any unknown number
