No answer is possible. As soon as you have one valid line, all points that are not on that line cannot be part of the solution set. Therefore the solution set cannot be all real numbers.No answer is possible. As soon as you have one valid line, all points that are not on that line cannot be part of the solution set.

This problem cannot be completed with real numbers because the highest possible product of two numbers that add up to 27, which is 13.5*13.5=182.25, is nowhere even close to 504.

Because that is the definition of irrational numbers: They are the numbers that cannot be written as a ratio of two integers! A fraction is a ratio of two integers.

No, they cannot with real numbers. With complex numbers it is possible.

Within the North American telephone system (USA, Canada, and certain Caribbean-ish islands), telephone numbers are uniformly 7 digits within each area code. There are 10 million possible 7-digit numbers; however, the quantity of possible phone numbers is lower than that, because not all 7-digit numbers are valid telephone numbers. In particular, the first digit cannot be a 0 or a 1; that immediately drops the number to 8 million. There are other combinations that are not permitted; for example, the first three digits cannot be 911. The exact list of unassignable numbers varies from location to location, but 7.8 million is a reasonable approximation of the quantity of potential telephone numbers in an area code.

If this is a question about prime numbers as the question category suggests, then never. Because a prime number cannot be negative and - if it were relevant - must be a whole number. I guess it would be possible to suggest: when a telephone number is a prime number?

A real telephone number is a telephone number that is live and connects to a landline or mobile device. There are different telephone numbers available that people don't recognise or insider not correct, this relates especially to non geographic numbers such as numbers like 0870, 0844 or when you need to dial the full area dialling code (STD) although the number should not need to be dialled in full. There are also false made up numbers such as on television shows when a real live telephone number cannot be displayed for obvious reasons.
