I'm pretty sure that is correct. 3 non collinear points always form a triangle.
Answer:
[r - 7][r + 7]
Step-by-step explanation:
Whenever you have a negative perfect square in the trinomial, like this one, that will tell you that you have to multiply conjugates, which are two monomials with <em>additive</em> <em>inverses</em><em> </em>inside. Additive inverses ALWAYS result in zero, which is your <em>B</em><em>.</em>

The numbers are: n, (n+2) and (n+4);
we can suggest this inequation:
84<n+(n+2)+(n+4)<96
Now, we solve this inequation:
84<n+(n+2)+(n+4)<96
84<3n+6<96
1)
3n+6>84
3n+6-6>84-6
3n>78
3n/3>78/3
n>26
2)
3n+6<96
3n+6-6<96-6
3n<90
3n/3<90/3
n<30
The solution is:
26<n<30
Then: n=28
The numbers will be: 28,30 and 32.
