A steel section of the Alaskan pipeline had a length of 58.5 m and a temperature of 18.0 °C when it was installed. What is its change in length when the temperature drops to a frigid -37.7 °C?
Apparently you forgot to read this before you posted your last several posts.

And not a single thought of your own. =(
i wanted to post the exact question so people will have all the information. and i am sorry for making anyone angry. i don't want it done for me, i just want what formulas to use. thanks to anyone/everyone that answers!! :)
No one is angry. You just need to include what YOU THINK or what you don't understand for each one so that our math tutors will know how to help you.
i did delta L = (alpha)(initial L)(delta T)
delta L = (12E-6)(58.5)(55.7) = 0.0391 m and i got it wrong. i tried that answer as negative too and it was still wrong. so does anyone know where i went wrong? i REALLY appreciate that help!!!
You need to post those thoughts (trial and error) with the appropriate question that you posted earlier. The math tutors won't find these things here.
I also get -0.0391
ok i will do that. thanks for the help!
I love how no one helped great job!
