The volume of a rectangular prism is 6x^3 -x^2 -2x. Which model could represent the rectangular prism?

Oksi-84 [34.3K]

The formula of a volume of a rectangular prism: V = lwh

l - length

w - width

h - height

We have the volume:

$V=6x^3-x^2-2x=x(6x^2-x-2)=x(6x^2+3x-4x-2)\\\\=x[3x(2x+1)-2(2x+1)]=x(2x+1)(3x-2)\\\\Answer:\ \boxed{A.\ Height:3x-2,\ Length:2x+1,\ Width:x}$

Is d y / d x the exact same as f ' ( x ) ? If yes, which is more commonly used?

Murrr4er [49]

It's dependent on the context. A book may ask you to find the f'(x) of a function and you may have to use a u sub in your problem which requires you to find the dy/dx of what you substitute. So in this case both would be used.
