Question

Can I please get steps. I have a lot of these to do and a good example would do. Please be specific and short to the point, I learn best that way. Thank you in advance!

Answer 1

This is just algebraic manipulation. The question asks you to isolate the equation for L.

Step 1) Multiply both sides by (R1+R2)

Step 2) Divide both sides by h

Doing those two steps will leave you with:

d(R1+R2)/h = L

So the answer is B.
