This question comes from a section on "Solving Problems With Quadratic Equations." I'm having problems with this, and I can't figure out why I can't get the right answer. I drew a digram with the information. I used the formula to find area wich is a=lw. The width of this is 'X'. The length is 'X+9'. The area is 90cm^2. I could not get the right answer for this. I set it up as 90=(x)(x+9) Then solved for x. The answer that I got was 81. The answer that I was supposed to get was 6. Anyone have any ideas of what I did wrong? Thanks in advance for the help!
