Answer:
60
Step-by-step explanation:
If it is an equilateral triangle the sides are equal
24-x = 5x
Add x to each side
24-x+x = 5x+x
24 =6x
Divide by 6
24/6 =6x/6
4 =x
Each side is 5x or 5*4 = 20
Add the 3 equal sides
20+20+20 = 60
The perimeter is 60
This would be a reflection.
Answer:
x= 4 y=11
Step-by-step explanation:
Let the length of one of the shorter pieces be

. Then, we know that two of the pieces are that length, and the third piece is

. Since these are all pieces of a rope, all we need to do to figure out the lengths is add all those together, solve for

, and then plug that back in to the desired lengths:



Shorter pieces:

Longer piece:
