Yes, ∆L = 5.80 x 10^{-4} m, the amount by which the length of C changes.

β is a variable and you don't know what it is yet. That's what you have to find.

Do this first: Expand out this equation: ∆L = ∆L

Hint: ∆L

I have to go now so I may not reply for a while.

i solve for the length of each material and the first part is 0.229 m while the second part is 0.071 m..

is that correct?

Ya that looks correct. I got β = 0.766.
