Answer:
I don't understand this. Could you please give more information?
Step-by-step explanation:
Using order of operations, I simplified this down to -24+22a.
I hope this helps, and let me know if you need more explanation!
That means there is about 38 fuels in each row because 454 divided by 12 = 37.83333333333333333 (exact number)

(x² + 3x - 1)(2x² - 2x + 1)
x²(2x² - 2x + 1) + 3x(2x² -2x + 1) -1(2x² - 2x + 1)
2x^4 - 2x³ + x² + 6x³ - 6x² + 3x - 2x² + 2x - 1
2x^4 - 2x³ + 6x³ + x² - 6x² - 2x² + 3x + 2x - 1
2x^4 + 4x³ - 7x² + 5x - 1
<span>(D)The result 2x4 + 4x3 − 7x2 + 5x − 1 is a polynomial.</span>
Given the figure of a cyclic quadrilateral
The sum of the opposite angles = 180
so, we can write the following equations:

we will find (x) from equation (1):
x = 180 - 100 = 80
We will find (y) from equation (2):
2y = 180 - 102
2y = 78
y=78/2 = 39
So, the answer will be:
x = 80
y = 39
