Dylan has a fish tank at home. He knows its height, h, is one inch less than twice the width, w, and the length, l, of the fish

pickupchik [31]

The right answer is: The binomial expression 2w + 6 represents the length of the fish tank.

Dylan has a fish tank, so we assume that this tank is a cube. In this way, the volume of the tank is given by this expression:

$V = w.h.l$

Where:

h: height

w: width

l: length

We know the following things:

FIRST. He knows its height, h, is one inch less than twice the width, w.

This can be expressed as the following equation:

$h=2w-1$

SECOND. The length, l, of the fish tank is seven inches longer than the height.

We can express this statement as follows:

$l=h+7 \\ \\ \therefore l=2w-1+7 \\ \\ \therefore l=2w+6$

By substituting $h \ and \ l$ in $V$ :

$V=w.h.l \\ \\ \therefore V=w(2w-1)(2w+6) \\ \\ \therefore V=w(4w^2-12w-2w-6) \\ \\ \therefore \boxed{V=4w^3-14w^2-6w}$
