A triangle has two sides of lengths 7 and 9. what value could the length of the third side be?
With a triangle the sum of its 2 smaller sides must be greater than its longest side and so if 7 and 9 are its smaller sides then its longest side could be 10
5,8,10,13

The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
10
It could be 12 because the sum of the 2 smaller sides of a triangle must be bigger than its largest side.
No. The sum of the lengths of two sides of a triangle must always at least slightly exceed the length of the third side, and the given numbers do not conform to this rule.
If any of its 2 sides is not greater than its third in length then a triangle can't be formed.

The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
Any triplet provided only that any two lengths are greater than the third.

The last side length could be between 4 units and 10 units inclusive.

No. The sum of any two lengths must be greater than the third length.
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
If the lengths of each pair of them add to more than the length of the third, they can form a triangle. If not, they cannot.
If (and only if) the length of each pair of sides is greater than the third side, then it is possible to make a triangle.
It could be 12 because the sum of the 2 smaller sides of a triangle must be bigger than its largest side.
