Answer:
the first.option is the right answer
Answer:
1) The polynomial
represents a sum of cubes
2) The polynomial
represents a difference of squares
Step-by-step explanation:
1) To find the polynomials represents a sum of cubes :
represents a sum of cubes
For
![=2^3x^3+1^3](https://tex.z-dn.net/?f=%3D2%5E3x%5E3%2B1%5E3)
![=(2x)^3+1^3](https://tex.z-dn.net/?f=%3D%282x%29%5E3%2B1%5E3)
Therefore
Therefore
represents a sum of cubes
2)To find the polynomials represents a difference of squares :
represents a difference of squares
For ![49x^2-25](https://tex.z-dn.net/?f=49x%5E2-25)
![=7^2x^2-5^2](https://tex.z-dn.net/?f=%3D7%5E2x%5E2-5%5E2)
![=(7x)^2-5^2](https://tex.z-dn.net/?f=%3D%287x%29%5E2-5%5E2)
Therefore ![49x^2-25=(7x)^2-5^2](https://tex.z-dn.net/?f=49x%5E2-25%3D%287x%29%5E2-5%5E2)
Therefore
represents a difference of squares
Answer:
A=1
Step-by-step explanation:
The formula to find the area of a circle is πr^2, meaning that you divide the diameter in half which is 1. So 1^1 is one. The area would be one.
Hope this helps :)
Answer:
9 because 3^3 is 9
Step-by-step explanation:
And since it's in the ones place nothing can stop it from being 9 since the tens or hundreds place don't contribute to the ones place.
A / B
= 80 / 8
= 10
Therefore the answer is 10
