The total cost for 9 bracelets, including shipping was $72. the shipping charge was $9. define your variable and write an equation that models the cost of each bracelet. use the equation you have written above determine the cost for each bracelet. show the algebraic steps that it takes to find the answer. provide your conclusion.

X=7

Step-by-step explanation:

9(x) + 9= 72

9(x) = 72 -9

9(x)= 63

(x) =63/9

X= 7

(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
