Bus a and bus b leave the bus depot at 4pm. Bus a takes 15 minutes to do its route and bus b takes 35 minutes to complete its route. at what time did they both get back to the bus depot together. give your answer as a 12-hour clock time

4.35pm is the later time, both buses were together back at the depot.

Reasons;

As bus b did not return his return route until 35 minute after departure.

We can say this was a return route taking 35 minute as the question does not point out length of time getting back. We therefore state it is a return route in the workings to explain how we found the answer.

Step-by-step explanation:

4.00 + 0.35 = 4.35 = b

4.00 + 0.15  = 4.15 = a

4.35 is the later time.

(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
