Step-by-step explanation:
He could be using either his bicycle, scooter, and the car. He could also be at either the school, garden or theatre. There are 3 possible methods of his transportation and places he could be. So Your Answer is 3.
The volume of the box is length * width * height
x^3 + 9x^2 + 6x - 16 = (x + 2) * width * (x + 8) = (x^2 + 10x + 16) * width
using synthetic division
-2 1 9 6 -16
-2 -14 16
-8 1 7 -8 0
-8 8
1 -1 0
Therefore, x^3 + 9x^2 + 6x - 16 = (x + 2)(x + 8)(x - 1)
Therefore, the width of the prism is x - 1
