Answer:
Each side is 2n - 5.
Step-by-step explanation:
The perimeter of an equilateral triangle is given by:
[tex]P=3s[/tex]
Where s is the length of each side.
The total perimeter is given by:
[tex]6n-15[/tex]
So, by substitution:
[tex]6n-15=3s[/tex]
Then the length of each side is:
[tex]s=\displaystyle \frac{1}{3}(6n-15)=2n-5[/tex]
Each side measure 2n - 5.
