Given:
The expression is

To find:
The product of prime polynomials which is equivalent to the given expression.
Solution:
We have,

Taking out the common factors, we get

It can be written as

![[\because a^3-b^3=(a-b)(a^2+ab+b^2)]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E3-b%5E3%3D%28a-b%29%28a%5E2%2Bab%2Bb%5E2%29%5D)


Therefore, the correct option is B.
Answer:
63
Step-by-step explanation:
k=y/x
y/x=k
y=k×x
y=7×9
y=63
1 yard = 3 feet
300 yards = (3 ft) x (300) = 900 feet
<em>1,000 feet</em> is larger than 900 feet. It's also longer and farther.
If x is the amount that Tanya paid for each item, then Tony's items would be x-2.25. So:
3x=4(x-2.25)
3x=4x-9
x=9
x-2.25=6.75
Tanya spent $9 on each item; Tony spent $6.75 on each of his items
