Ive been working on this problem for about 2 hours now and I can not get the right critical values. Please help.
I found the derivative of the equation is sqrt(3/2) x-3/8 (10-3 x) and ive checked this over many times so im pretty confident in my answer.
The Attempt at a SolutionIm sure what to do with the √2 and the 8 on the bottom. I did it with disregarding them and I now that's wrong but it cam up with the closet answer. I got it to the point of x+9x=30/√3 I get lost after that and im pretty sure my work before this point is wrong also.
im just trying to find the smallest area a square and triangle with perimeter some of 10 can be.
