Answer 1

Hint:
Sum of any wo sides of a triangle is greater than the third side

Answer 2

i am really confused on what i am doing

Answer 3

First assum n+6 is the largest side

Answer 4

So, n+6 < n+3 + 3n-6

Answer 5

no i did that i dont know what to do after

Answer 6

n+6 < n+3 + 3n-6
15<3n
n>5

Answer 7

wait so is that the answer?

Answer 8

3n-6>n+6 + n+3
n>15

Answer 9

n+3 > n+6 +3n-6
n<1

Answer 10

So, the answer is
n<1 and n>5

Answer 11

o so it has to be smaller than 1 and greater than 5?

Answer 12

yes
