I was hoping to receive some help I'm trying to solve for the variable r.
136.89=65.33 * ((r + 4) * (r + 4) - (4 * 4)) / 12
Thanks in advanced.
I'm sorry it still has me confused. It has been a few years since I have had to touch an equation like this. I seem to what to start in the wrong directions by multiple by 12 to cancel and then divide by 65.33. In your equation I'm not sure where the 3x comes from. Any suggestions?
