Well, since its isoceles triangle so two equal sides. its either 3 or 7. There is a theorem that states two sides added must be greater than the third. so if the third side is 3. it would be 3+3=6, less than 7, incorrect. therefore the correct side is 7. so the sides are 3, 7, 7. you can add them to confirm the theorem.

Answer:

3 < b-a < 7

Step-by-step explanation:

The maximum difference will occur when the smallest 'a' value is subtracted from the largest 'b' value:

9 -2 = 7

The minimum difference will occur when the largest 'a' value is subtracted from the smallest 'b' value:

7 -4 = 3

So, the possible range of values of b-a is ...

3 < b-a < 7
