1. ## Quadratic Equation Word Problem..

hey guys (again )
so i just wanna make sure i did the question right...
i've attached a picture of the question and the diagram that shows the situation,
and my half of my solution is on the picture as well;
if you guys could let me know if i did the question right, and if not, what i did wrong that'd be awesome
or you guys could just type the solution, & i'll check what i did wrong :P

thanks guys i have a test tmrw, so i wanna get over 90 to boost my mark (i got a 77 on my last test, sooooo disappointed )

Question:
Lila is creating dog runs for her dog kennel. She can afford 30m of chain-link fence to surround four dog runs. The runs will be attached to a wall, as shown in the diagram. To achieve the maximum area, what dimensions should Lila use for each run and for the combined enclosure?

THANKS AGAINN !

2. Can length be negative?
l = -3?
Check the step when you factored out -5.

Make sure to answer the question asked:
What are the dimensions for each run and for the entire enclosure?

Other than that looks good. Ace that test

3. oooooooh !
i see what i did.. haha thanks
