A high school Philanthropy Club is collecting plastic waste which will be used to create benches for a local park. The volume of
Zolol [24]

Answer:

The expression 7x represents the height of the container.

Step-by-step explanation:

From the question:

We are being informed that; if the length of the container is half of a foot longer than its width.

Let the width be x;

Then the length of the container can now be ; x+1/2

We all known that the volume of a rectangular prism is : V= l×w×h

here;

l = length

w = width

h = height  

If we rewrite the given expression :

\mathbf{7x^3+3.5x^2};

Then we factor we make a similar coefficient  of  the above equation, the  remaining entities left in the parenthesis should be a linear term  with a leading coefficient of 1 to match the expression for the length of the container.

i.e

\mathbf{7x^3+3.5x^2}} \\ \\\mathbf{7x^2(x+1/2)}  \\ \\\mathbf{7*x*x*(x+1/2)}

Hence, if the length of the container is half a foot longer than its width, x, then the expression 7x represents the height of the container.
