Answer:
5) The third side must be more than 4 and less than 14.
6) The third side must be more than 3 and less than 13.
Step-by-step explanation:
The third side must be more than the difference and less than the sum of the two numbers.
5) 9-5=4
9+5=14
So the third side must be more than 4 and less than 14.
6) 8-5=3
8+5=13
So the third side must be more than 3 and less than 13.
