Two combine harvesters are able to harvest the crop from 320 acres in a certain amount of time. working together for the same time, how many acres can be harvested by: 3,4 and 12. combine-harvesters will mark brainliest!

2=320

320/2=  160

Key:

*1=160

3*160=480

4*160=640

12*160= 1920

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."

step-by-step explanation: yes
