As an estimation we are told 5 miles is 8 km.
Convert 12.5 miles to km.

20.1168

Step-by-step explanation:

20 miles

Step-by-step explanation:

1 mile = 1.60934 km

12.5 miles

= 12.5 x 1.60934

= 20.11675 miles

~ 20 miles ( apporximately )

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."
