Find the mean in terms of x. 3x-2, 12x+9 and -6x+5. Make sure you simplify your final answer and write your x term first in your final answer. (like the homework from Monday)

  mean = 3x +4

Step-by-step explanation:

As with numbers, the mean is the sum divided by the number of constituents of the sum.

  mean = ((3x -2) +(12x +9) +(-6x +5))/3

  = (9x +12)/3

  mean = 3x +4

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

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."
