A. Not a proper counterexample as 3 and 5 aren't the same number. We can rule out choice A.
B. We can rule out choice B since we're not multiplying here
C. We are multiplying the same value with itself but the result is even. We can rule this out.
D. This is a proper counter example. We have the same number (5) multiplied by itself leading to a result that is not even. It contradicts the initial claim.
Answer: Choice D
Answer:
<h2>10.9955742876</h2>
Step-by-step explanation:

I do K12 7th grade and it has really brought my grades up! One thing I have noticed though is the work is more advanced then the work at a normal school. At first I had alot of trouble getting used to the system but after awhile it's very simple. I really like K12 because it let's you learn at your own pace. if you have any questions about K12 I would be happy to answer.
