Question

Select all the correct answers.

Answer 1

If x is the third side, then x is between 5-3 = 2 and 5+3 = 8. The value of x cannot be equal to 2, or it can't be equal to 8 either. 

So 2 < x < 8. The following answer choices fit this inequality: 
choice B) 6 cm
choice C) 4 cm

The other answer choices are outside of the interval 2 < x < 8

So that's why the answers are choice B and choice C.

Answer 2

I think it is 6 and 4
