Answer:</h3>
The expression is undefined when x=3 or -3
<h3>
Solution:</h3>
- An expression is undefined when it's divided by 0.
- In order to make the denominator equal 0, we need to subtract 9-9.
- Notice that x is squared.
- So x times itself should equal 9. What number is it?
- That's right, 3.
- So we have
- 9-(3)^2=9-9=0
- There's also another solution: x=-3 (-3•(-3)=9

3 + 8 = 11 > 9
9 + 8 = 17 > 3
Thus the 3 lengths can form a triangle
