Question

The perimeter of an equilateral triangle is 18p - 24. Write an expression to represent the length of each side.

Answer 1

6p -8

Explanation:

The three sides of an equilateral triangle are all the same length. (This is the literal meaning of "equilateral.") So, the length of one side is 1/3 the total length.

each side =
`(18p-24)/(3)=(18p)/(3)-(24)/(3)=6p-8`
