A survey asked a random sample students if they estimated they spent more or less than an hour a day on social media. Results are shown in the table below, but some
values are missing. Fill in the missing values.

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.

Me with this one question, and i'll upvote the brainliest answer

Determine which expressions represent real numbers and which expressions represent complex number. asaaap! plis!
