uysha [10]

The machine was operated for  4.5 hours

A machine uses gasoline at a rate of 1/5 gallon per hour

The number of hours it will take the machine to use 9/10 gallon can be calculated as follows

1/5 = 1

9/10= x

cross multiply

1/5x= 9/10

0.2x= 0.9

x= 0.9/0.2

x= 4.5

Hence the machine was operated for 4.5 hours

Which polynomial correctly combines the like term and express the given polynomial in standard form
ankoles [38]

Answer:

8mn^5 - 2m^6 + 5m^2n^4 - m^3n^3 + n^6 - 4m^6 + 9m^2n^4 - mn^5 - 4m^3n^3 = -6m^6  - mn^5 - 5m^3n^3 + 14m^2n^4 + 8mn^5  + n^6

Step-by-step explanation:

Given

8mn^5 - 2m^6 + 5m^2n^4 - m^3n^3 + n^6 - 4m^6 + 9m^2n^4 - mn^5 - 4m^3n^3

Required

Correctly combine the like terms

We have:

8mn^5 - 2m^6 + 5m^2n^4 - m^3n^3 + n^6 - 4m^6 + 9m^2n^4 - mn^5 - 4m^3n^3

Collect like terms (in decreasing degrees of m)

- 2m^6 - 4m^6  - mn^5- m^3n^3  - 4m^3n^3+ 5m^2n^4  + 9m^2n^4 + 8mn^5  + n^6

-6m^6  - mn^5 - 5m^3n^3 + 14m^2n^4 + 8mn^5  + n^6

So:

8mn^5 - 2m^6 + 5m^2n^4 - m^3n^3 + n^6 - 4m^6 + 9m^2n^4 - mn^5 - 4m^3n^3 = -6m^6  - mn^5 - 5m^3n^3 + 14m^2n^4 + 8mn^5  + n^6
