Kendra charges $11 to shovel a driveway. She shoveled 4 driveways on Saturday and then some more on Sunday. She made $143 for the weekend.
How many driveways did she shovel on Sunday?
Choose two answers: one for the equation that models this situation, and one
for the correct answer.
A. Equation: 11(4 + x) = 143
B. 9 driveways
C. 13 driveways
O D. Equation: 4(11 + x) = 143

A and B

Step-by-step explanation:

The 11 should be multiplied after 4 + x because the (4 + x) is the total amount of driveways she shoveled. If you solve for x using A's equation, you should get 9 as your answer. Therefore, your answer choices are A and B.

(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
