That makes sense now. I never tried distributing it...

I was actually supposed to show that the four properties were true. and I thought if all cases were true then it was an equivalence relation.

comment Proving inequalities by using induction
I see how you got $3k+2$ now but why would it make sense to substitute something that is less than $k^2$ into the right hand side when we are trying to prove that it is greater than $k+2$?

What do you mean by substitute what I got from the hypothesis? I don't understand where the $3k+2$ came from.

comment Prove divisibility by using induction
When I expand, I get $6m+3k^2 +3k +6$. How would I use that to show $(k+1)^3+5(k+1)$?
