The length of the second side of a triangle is 24 cm shorter than twice the length of the first side. Using f for the first side and s for the second side, translate the sentence into an equation.

Question

butterflydreamer · Answer

Let f = first side, s = second side.
From the first line of your question it says:
The length of the second side (s) is 24 cm shorter than TWICE the length of the first side (f).

This means that the second side (s) = 2 times the first side (f) - 24 

[ we subtract 24 because it says that the side s is 24 SHORTER so we need to do -24]

so would it be s=2f-24 for the equation

that's correct :)
