You have two identical lenses, each with a focal length of 16 cm, and you have a 13 mm tall object which you would like to image. Let's say you set up the object at x = 0 along your optical axis and you place the two lenses at x = 8 cm and x = 24 cm, respectively. Where will the final image be located and what is its height (use a negative value for the height if it is inverted). What is the magnification.
