I have a question about #8, The question tell you that the rate that the side of an equalaterial triangle is decreasing at is 2cm/s and that you have to find the rate the area is decreasing when it is 100cm^2. I assumed that you would use the equation that finds the area of an equalaterial in relation to the side but I keep getting a different answer Any suggestions as to where I'm messing up would be very much appreciated.

Hope everyone is enjoying their summer. Here's a random post that reminded me of this forum's existence.

I've finally moved on an accepted the truth
