between 32 and 38 pages read
Scatter plot on a first quadrant coordinate grid. The horizontal axis is labeled Age, in years. The vertical axis is labeled Number of pages read. Points are plotted at (eight, thirty-two), (eight, thirty-four), (eight, thirty-six), (eight, thirty-eight), (nine, thirty-two), (nine, thirty-four), (nine, thirty-six), (nine, thirty-eight), (ten, thirty-four), (ten, thirty-six), (ten, thirty-eight), (eleven, forty-two), (twelve, forty-four), (thirteen, fifty), (thirteen, fifty-two), (fourteen, forty-six), (fifteen, fifty-four), (sixteen, fifty-eight), (seventeen, fifty-eight), (seventeen, seventy-two).

8121 because

130,000 divided by 16 is 8121

(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
