Answer:

The height of the container is [tex]7x\ ft[/tex]

Step-by-step explanation:

Let

L ------> the length of the rectangular container

W ----> the width of the rectangular container

H ---> the height of the rectangular container

we know that

The volume of the rectangular container is

[tex]V=LWH[/tex] ------> equation A

we have

[tex]W=x\ ft[/tex]

[tex]L=(x+0.5)\ ft[/tex]

[tex]V=7x^{3}+3.5x^{2}[/tex]

substitute the values in the equation A

[tex]7x^{3}+3.5x^{2}=(x+0.5)(x)H[/tex]

Factor the term x in the left side

[tex](7x^{2}+3.5x)(x)=(x+0.5)(x)H[/tex]

Simplify

[tex](7x^{2}+3.5x)=(x+0.5)H[/tex]

Factor the term 7x in the left side

[tex](7x)(x+0.5)=(x+0.5)H[/tex]

Simplify

[tex](7x)=H[/tex]

Rewrite

[tex]H=7x\ ft[/tex]
