These problems are confusing me because the way they have each step listed out, and how they use dw. Can someone give me an explanation for these.

For the first one: If Then, So, we have f(x)dw = dx but we need f(x) in terms of w. We know that So, Using this, And f(w) = 2w/25 Using this in the integral: Hence, Can you continue now?
Thanks! Maybe if I hadn't been staring at this problem all day I would have realized I needed to integrate back to w. I think I can do the next one now
