45 rpm
there are several speeds for vinyl records, but for common formats it is 33 rpm, 45 rpm, 78 rpm and actually 33 1/3 rpm. that's what they were called 45's because they made 45 revolutions or rounds but it's actually revolutions per minute.

The version on vinyl, or a record (the LP at 33.3 RPM). I remember when there were 45 RPM records, usually just 1 song each side, and LP records or albums, which had the Long Playing version of songs, with, sometimes, repeated choruses, etc...Earlier vinyl records had 78 RPM records also.
8-Track
I would, unless the seller stated that the cover would not be with it. A few exceptions would be 78 rpm records which usually did not have covers, only a paper sleeve. Ditto for 45 rpm's. And Vinyl Picture Discs which sometimes came only in a clear vinyl sleeve.
