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 × sides
Given Perimeter is [tex]35y^4-65x^3[/tex] inches.
Thus, [tex]35y^4-65x^3[/tex] = 5 × 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.
