To four times a certain number i add 16 and the result is 28. Find this number

(1): "s2"   was replaced by   "s^2".  2 more similar replacement(s).

(2): Dot was discarded near "8.f".

Step-by-step explanation:

i believe

The certain number would be 3

Step-by-step explanaition

4 times 3 is 12 plus 16 is 28. hope it helps

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."
