Question 28315
A square has an area of 9x^2+12xy+4y^2. What is the length of a side of the square?

I know the formula is A=s^4...
NO IT IS A= S^2...NOT S^4..WHERE S IS THE SIDE.
however I think that this answer is 3x+2y? Is that right by any chance? 
VERY CORRECT ....IT IS SQUARE ROOT OF 
9x^2+12xy+4y^2.=(3X)^2+(2Y)^2+2*(3X)*(2Y)=(3X+2Y)^2
HENCE S=3X+2Y....GOOD GUESS YOU MADE..
