I think maybe it’s c? Sorry if I’m wrong
Answer:
One
Step-by-step explanation:
A, B, R and C lie on the same plane, while the others do not
The subtraction gives -7x^2( x + 1) - 3
<h3>What are algebraic expressions?</h3>
Algebraic expressions are expressions are expressions that are made up of factors, terms, variables and constants.
They also consist of arithmetic operations.
We have to subtract (6x^3 − x^2 + 8x + 5) from (−x^3 − 9x^2 + 2)
It is written as;
(−x^3 − 9x^2 + 2) - (6x^3 − x^2 + 8x + 5)
−x^3 − 9x^2 + 2 - 6x^3 + x^2 - 8x - 5
collect like terms
-x^3 - 6x^3 - 9x^2 + x^2 + 2 - 5
Add like terms
-7x^3 - 7x^2 - 3
To simply further
-7x^2( x + 1) - 3
Thus, the subtraction gives -7x^2( x + 1) - 3

Answer:
Each classroom receives 3 gallons of cider
Step-by-step explanation:
<u><em>The question in English is</em></u>
Mavis has 15 gallons of cider that it distributes to 5 classrooms. How much cider does each classroom receive?
To find out how much cider each class receives (assuming it is equally divided), divided the total gallons of cider by the number of classrooms (unit rate)
Let
x ----> the total gallons of cider
y ----> the number of classrooms
so
![\frac{x}{y}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D)
we have
![x=15\ gal\\y=5\ classrooms](https://tex.z-dn.net/?f=x%3D15%5C%20gal%5C%5Cy%3D5%5C%20classrooms)
substitute
![\frac{x}{y}=\frac{15}{5}=3\ \frac{gal}{classroom}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%3D%5Cfrac%7B15%7D%7B5%7D%3D3%5C%20%5Cfrac%7Bgal%7D%7Bclassroom%7D)
