Explanation

The length of any side of a triangle is larger than the difference of the other sides, and is smaller than the sum of the other two sides.

Say the third side is x. 6 – 4 < x < 6 + 4 => 2 < x < 10.

The possible integer values of x are 3, 4, 5, 6, 7, 8, & 9. We can have 7 possible integer values for x.

**Correct choice is B.**

Say the third side is x. 6 – 4 < x < 6 + 4 => 2 < x < 10.

The possible integer values of x are 3, 4, 5, 6, 7, 8, & 9. We can have 7 possible integer values for x.

Two triangle sides, both alike in dignity…
