2(A+B)+20d-5d
The magnification of a lens is calculated using the formula M = 1 + D/f, where M is the magnification, D is the lens power in diopters (20D in this case), and f is the focal length of the lens in meters. Without knowing the focal length of the lens, we cannot determine the exact magnification.
The nail length The strength of the nail The shape of the nail occasions
An 8 penny nail (abbreviated as 8d) is 2.5 inches in length. A 10 penny nail (10d) is 3 inches in length.

Yes, you can. Any EF and EF-S lens will work on 20D.

You cannot record video/sound with Canon EOS 20D. It takes only photos with RAW/jpg output format.
If you mean: 3d2+20d+12 then it is (3d+2)(d+6) when factored with the help of the quadratic equation formula
