Answer 1

Any and all help is appreciated!!!

Answer 2

Do you use the Newtonian or Gaussian formulas in your class?

Answer 3

We have had lessons on both, I myself prefer Gaussian but thats just me.

Answer 4

Ok. You have what you need, the object distance and the focal length. Plug them in and solve for the image distance.
