Ellie rents a pressure washer and a paint
sprayer. She is charged $76 per day for
the pressure washer and $104 per day
for the paint sprayer. Which algebraic
expression represents Ellie's cost to rent
the pressure washer and paint sprayer for
d days?

76d + 104d

Step-by-step explanation:

Ellie is charged $76 per day for the pressure washer

Ellie is charged $104 per day for the paint sprayer

The number of days = d

Ellie would be charged 76 * (d) for the pressure washer

Ellie would be charged 104 * (d) for the paint sprayer

If you add them together, it is 76d + 104d

(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
