thanks but how do I solve it?

It is 6 feet longer than it is wide, so you can write an expression for both the length and the width.

(w+6)^2+w^2=30276..... w^2+12w+36+w^2=30276......2w^2+12w+36=30267

i was trying to use the quadratic formula but i wasnt sure what to do and my numbers were wayyyyyy big

Great 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.

The numbers do get big, but you can handle it, with your calculator's help.

when 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

It is not negative. You dropped a negative on the floor....look around, I'm sure it is still nearby. :)

gypsy1274 Group TitleBest ResponseYou've already chosen the best response.1
One you get all the terms to the left side, the constant term will be negative.

I divided the whole equation by 2 to keep the numbers smaller. \(w^2+6w15120\)
 one year ago

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

madsmckell Group TitleBest ResponseYou've already chosen the best response.0
the answer in the back of the book is 120 by 126

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

gypsy1274 Group TitleBest ResponseYou've already chosen the best response.1
The 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.
