Answer:
Statement 4 is incorrect.
Step-by-step explanation:
#4 is incorrect. This statement is assuming that both 3x+5 and 4x are equal, but the correct way to use them and achieve 180 (definition of supplementary) degrees is by writing it as: 3x+5 + 4x = 180. (I spaced the 3x+5 and 4x to make it clear that these are two angles added together.) With this equation, you will be able to find the x and the substitute it back in to complete the equation.

Answer:
Part A:

Part B:
The closure property describes cases when mathematical operations are CLOSED. It means that if you apply certain mathematical operations in a polynomial it will still be a polynomial. Polynomials are closed for sum, subtraction, and multiplication.
It means:
But when it is about division:
<u>Example of subtraction of polynomials:</u>
<u />

<u />
<u />
Step-by-step explanation:
<u>First, it is very important to define what is a polynomial in standard form: </u>
It is when the terms are ordered from the highest degree to the lowest degree.
Therefore I can give:

but,
is not in standard form.
For this question, I can simply give the answer:
and it is correct.
But I will create a fifth-degree polynomial using this formula

Also, note that
