Question

If n + 2, 5, and 9 represent the lengths of the sides of a triangle then < n

Answer 1

Answer:

n>2      (see below)

Step-by-step explanation:

Triangle side rule says    n+2   + 5   must be greater than 9

    n+2   +5  > 9

    n > 2      

      (but it must be less than 12   o/w   5 + 9 will not be greater than n+2)
