Question

The perimeter of an equilateral triangle is 6n - 15. Write an expression to represent the length of each side.

Answer 1

Answer:

Each side is 2n - 5.

Step-by-step explanation:

The perimeter of an equilateral triangle is given by:

$P=3s$

Where s is the length of each side.

The total perimeter is given by:

$6n-15$

So, by substitution:

$6n-15=3s$

Then the length of each side is:

$s=\displaystyle \frac{1}{3}(6n-15)=2n-5$

Each side measure 2n - 5.
