A race car driver practices over four sessions. His finish times for specified distances are given. He wants to compare how fast he was driving in each session. Place the finish times of each session in order from fastest to slowest according to the unit rate in kilometers per second. 8 kilometers in 83 seconds 15 kilometers in 168 seconds 18 kilometers in 198 seconds 10 kilometers in

10 km in 97 seconds, 8 km in 83 seconds, 18 km in 198 seconds, 15 km in 168 seconds.

Step-by-step explanation:

The unit rate for each session can be found by dividing the kilometers by the seconds. Then, make an equivalent fraction by dividing both the numerator and denominator by the numerator. This will show how many seconds it took to finish 1 kilometer during that session.

explanation:

(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
