The expression that represents the width of the box is (x - 1) , the correct option is (b) .
In the question ,
it is given that ,
the Volume of the rectangular prism is = x³ + 9x² + 6x – 16
the measure of the length of the box = x+2
the measure of the height of the box = x+8
formula for Volume of Prism is
Volume = l × w × h
where l = length of the prism,
w = width of the prism and
h = height of the prism.
Substituting the values ,
we get ,
x³ [tex]+[/tex] 9x² [tex]+[/tex] 6x – 16 [tex]=[/tex] (x [tex]+[/tex] 2) * (x [tex]+[/tex] 8) * width
On dividing the equation (x³ + 9x² + 6x – 16) with (x+2)
and then dividing the result with (x+8) , we get
width = (x-1) .
Therefore , The expression that represents the width of the box is (x - 1) , the correct option is (b) .
The given question is incomplete , the complete question is
The volume of a rectangular prism is represented by the function x³ + 9x² + 6x – 16. The length of the box is x + 2 while the height is x + 8. Find the expression representing the width of the box
(a) x - 4
(b) x - 1
(c) x + 1
