Can someone explain what the answer is to this and how? Thank u!!!
Sloan [31]
The answer is D.
You cannot factorise it as there are two different terms being squared with the middle term containing both. Also, if you expand any of the brackets in the questions you will not get the original equation so non of them are right so it has to be D. :)

Using the definitions of even integer and odd integer, give a proof by contraposition that this statement is true for all intege
kvasek [131]
Suppose n is even, i.e. there is some integer k such that n=2k. Then

3n-5=3(2k)-5=6k-5=6k-6+1=2(3k-3)+1=2K+1

where K is just some other integer. Therefore 3n-5 is odd, proving the contrapositive, and so the original statement is also true.
