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

  6p -8

Step-by-step 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 =

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

x = 12

y = 15
