Best ResponseYou've already chosen the best response.1It is 6 feet longer than it is wide, so you can write an expression for both the length and the width.

Best ResponseYou've already chosen the best response.1Great job! Find a calculator, you are going to need it. :) The quadratic formula is what you will need. I'm still working through it. Before you get to that, get all terms to the left side of the equation and set it equal to 0.

Best ResponseYou've already chosen the best response.0when i do the quadratic inside the root is negative so how would i simplify it??? isnt the quadratic formula b plus or minus the root of b^24ac all over 2a

Best ResponseYou've already chosen the best response.1It is not negative. You dropped a negative on the floor....look around, I'm sure it is still nearby. :)

Best ResponseYou've already chosen the best response.1One you get all the terms to the left side, the constant term will be negative.

Best ResponseYou've already chosen the best response.1I divided the whole equation by 2 to keep the numbers smaller. \(w^2+6w15120\)

Best ResponseYou've already chosen the best response.0but when you put in 15120 it is negative in the root soo it wont workkk

Best ResponseYou've already chosen the best response.0so still not sure how that works when what ever i root comes out to be a decimal

Best ResponseYou've already chosen the best response.1The answer in the back of the book is correct. \[\dfrac{b \pm \sqrt{b^24ac}}{2a}\] \[w^2+6w15120\] \[\dfrac{6 \pm \sqrt{6^24(1)(15120}}{2(1)}\] remember that a negative times a negative is a positive.
