Does anyone know how to do
a student scored in the 85th percentile on her chemistry exam. what does this student's score mean in relation to those of the other test takers?
her score was better than those of 85% of all test takers.
her score was worse than those of 85% of all test takers.
her score on the exam was 85%.
her score was in the top 85% of all test takers' scores.

i believe it the 'her score on the exam was 85%'. the question is worded odd but that one seems most fitting and logical to me

(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
