The volume of a rectangular prism is the product of its dimension.
The missing side length is 2x + 5.
The volume is given as:
[tex]\mathbf{V = 2x^3 + 17x^2 + 46x + 40}[/tex]
Let the missing side be y.
So, we have:
[tex]\mathbf{V = (x + 2) \times ( x + 4) \times y}[/tex]
So, we have:
[tex]\mathbf{(x + 2) \times ( x + 4) \times y = 2x^3 + 17x^2 + 46x + 40}[/tex]
Factorize
[tex]\mathbf{(x + 2) \times ( x + 4) \times y = (x + 2) \times (x + 4) \times (2x +5)}[/tex]
Cancel out common factors
[tex]\mathbf{y = (2x +5)}[/tex]
Remove brackets
[tex]\mathbf{y = 2x +5}[/tex]
Hence, the missing side length is 2x + 5.
