Answer:
3
Step-by-step explanation:
mhm for your brother
anyways...
2x-3+6x = 21
Adding like terms
8x -3 = 21
Adding 3 on both sides
8x = 24
Dividing both sides by 8
x = 3
Check the picture below.
the segment LOJ is a diameter, and therefore the arcLCJ made by that diameter will have a central angle of 180°.
that simply means that the arcLC is 180 - 94, or 86°.
the ∡LJC is an inscribed angle that is intercepting the arcLC, and therefore, by the inscribed angle theorem, it'll be half of arcLC.
~Hello There!~
Finding the perimeter simply means adding all the sides together.
31 + 81 + 31 + 81 = 224 cm
Yes, you are correct.
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^

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>

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

For
