The number of mold cells doubles every 12 minutes. At this moment, there are x mold cells present on a piece of bread. Which of the following represents the number of mold cells present one hour from now?

Step-by-step explanation:

Suppose that at time we have x mold cells. We are told that after 12 minutes the amount present is double. That is a we have 2x cells. Then, at we have (2x)*2 = 4x. We can continue as follows

we have (4x)*2 = 8x.

we have (8x)*2 = 16x

(one hour later) we have (16x)*2 = 32x.

So after one hour from now we have 32x cells.

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."
