)the box plot shows the number of years during which 16 schools have participated in a marching band competition: a box plot is titled years of participation and labeled years. number line from 0 to 10 with primary markings and labels at 0, 5, and 10. the box extends from 3 to 7 on the number line. there is a vertical line at 5. the whiskers end at 1 and 10. at least how many schools have participated for 3 to 7 years?

(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
