Answer:

Option (4) is correct.

The length of one side of the sandbox is  [tex]7y^4-13x^3[/tex]  inches.

Step-by-step explanation:

Given :  Joan is building a sandbox in the shape of a regular pentagon. The perimeter of the pentagon is [tex]35y^4-65x^3[/tex] inches.  

We have to find the length of one side of the sandbox.

Since, given sandbox is in shape of a regular pentagon.

So, Perimeter of pentagon is 5 times sides.

Perimeter of pentagon = 5 Ă— sides

Given Perimeter is [tex]35y^4-65x^3[/tex] inches.  

Thus, [tex]35y^4-65x^3[/tex] = 5 Ă— sides

Divide both side by 5, we get,

[tex]7y^4-13x^3[/tex] = sides

Thus, The length of one side of the sandbox is  [tex]7y^4-13x^3[/tex]  inches.
