Agroup of students wants to determine the favorite snack food at their school. they know they should use a sample because the student population at their high school is 5,000. what is the best way for them to get a random sample of 100 students? ask the teachers at the school their opinions. ask every 20th student until they reach 100 students. ask the first 100 students that get off the bus in the morning. ask all the students in the cafeteria during one of the four lunch periods.

(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

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
