Meredith lives in apartment building in Boston. There is an elevator that starts at ground level and runs to the roof of the building. The elevator travels 12\frac{3}{4} feet between each level. Meredith takes the elevator from the ground level to the 7th level, then continues to the roof. How many levels will the elevator still have to travel to reach the roof if the building is 191.25 feet tall?

(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

the answer is b

the equation is not included but the answer is (1.50, 2.00, 2.75)
