Answer:
Subtracting Polynomials is very similar to adding polynomials. In fact, we will be changing the subtraction problem to an addition problem.
In the Pre-Algebra section of the website, we started out by reviewing integers.
We said, "When you subtract integers, you must add the opposite. We also talked about the Keep - Change- Change Rule. That rule applies to polynomials as well.
Take a look at these examples that show you how to rewrite the problem as an additional problem.

Notice they say Plastic cups. Cups and plastic cups are not the same. Cups are a form of measurement while plastic cups are a container. This is not a true statement. Hope this helps!
Answer: a) 
Step-by-step explanation:
We know that the volume of an oblique pyramid is given by :-
If the volume of an oblique pyramid with a square base is V units³ and the height is h units.
Then, we have
Multiply 3 on both sides , we get
Divide both sides by h , we get
i.e. 
Hence, the expression represents the area of the base of the pyramid =
Hence, the correct answer is a) 3 v/h units^2
It should be 13 since 13+8 = 21. 21-7 = 13
