Solve this for me and explain it to me. cause i'm confused.

28

Step-by-step explanation:

If g is the number of green marbles, and b is the number of blue marbles, then:

g + b = 36

g = 4 + 3b

Solve the system of equations.  Using substitution:

(4 + 3b) + b = 36

4 + 4b = 36

4b = 32

b = 8

Therefore:

g = 28

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
