Respuesta :

Problem 14 and problem 16 are missing the diagrams needed to answer the questions. Thankfully, there is enough info for me to answer problem 15, which I'll do so below.

------------------------------

If we have a triangle with side lengths a,b,c then we can write this compound inequality

b-a < c < b+a

If we knew the value of a and b, then we can find a range for c.

In our case, a = 5, b = 12, c = n, so,

b-a < c < b+a

12-5 < n < 12+5

7 < n < 17

The value of n is between 7 and 17. The value of n cannot equal 7, and it also can't equal 17 either.

------------------------------

Final Answer for problem 15 is choice C) 7 < n < 17
