Prove:

Levart [38]

Given the statement, "If $n^2$ is odd, then $n$ is odd," its contrapositive claims that, "If $n$ is not odd, then $n^2$ is not odd."

So assume $n$ is not odd, i.e. $n$ is even. This means there is an integer $k$ for which $n=2k$ . Squaring this gives $n^2=(2k)^2=4k^2$ .

Well, we can write $4k^2=2(2k^2)$ , and $2k^2$ is just another integer, which means $4k^2=(2k)^2=n^2$ must be even.

Is the figure a rectangle? Explain.

Sphinxa [80]

Here is the first sign that should tell you this isn't a rectangle.

d=_/w^2+l^2 is the equation to solve the diagonal of a rectangle

if you plug in 21 and 20, d would equal 29 not 28 so for that reason alone it is not a rectangle.

I am about 90% sure the correct answer is B. I hope this helps let me know if I was right.

Option B!
