The sum of two polynomials is -yz to the second power-3z to the second power-4y+4. If one of the polynomials is y-4yz to the sec
balu736 [363]

Answer:

- 5yz^2 - 3z^2 - 5y + 7

Step-by-step explanation:

The polynomial is:

-yz^2-3z^2-4y+4   ( 1 )

this polynomial is the result of the sum of two polynomials, one of them given by

y-4yz^2-3     ( 2 )

if you find to know what is the other polynomial, you can take the difference between the polynomial (1) and (2). It is necessary to take the difference between simmilar terms, as follow:

 - yz^2 - 3z^2 - 4y + 4

<u>- (4yz^2          + y   - 3  )</u>

<u />

 - yz^2 - 3z^2 - 4y + 4

<u> - 4yz^2           - y   + 3  </u>

- 5yz^2 - 3z^2 - 5y + 7

hence the other polynomial is - 5yz^2 - 3z^2 - 5y + 7

alexira [117]
A is the answer because he works 2 jobs cleaning pools and mowing lawns so you would add their times together and he works 4 days a week so you would take this and multiply it by the amount of hours he works.

If you need an answer to the answer would be he works a total of 28hrs over a four day period
