The issue isn't whether we can source those things. The issue is that we _should not_ give individual references for facts like that. Because:
* Attaching a source to them gives the false impression that they are controverisal, or that the source given is going to say something particularly profound about the topic. If too many footnotes are used, it's no longer possible to tell which footnotes are actually interesting to check and which are for facts that nobody disagrees with. This makes the footnotes much less useful for a reader, who can no longer use them to build intuition about the material.
* Doing web searchs to find sources leads to a random hodgepodge of dozens of references, each used just to source one simple fact. This is an awful writing style, and often leads to the use of poor references (web pages, etc.) found in the web searches. It's better to stick to professionally published textbooks and articles.
* Especially in the sciences and mathematics, sourcing trivial facts like you listed above is completely odds with accepted practices in the field.
[[Wikipedia:Scientific citation guidelines]] has a nice explanation of the things that should be sourced. In particular, regarding basic facts like the ones above, it says:
The verifiability criteria require that such statements be sourced so that in principle anyone can verify them. However, in many articles it is cumbersome to provide an in-line reference for every statement. In addition, such dense referencing can obscure the logical interdependence of statements. Therefore, in sections or articles that present well-known and uncontroversial information – information that is readily available in most common and obvious books on the subject – it is acceptable to give an inline citation for one or two authoritative sources (and possibly a more accessible source, if one is available) in such a way as to indicate that these sources can be checked to verify statements for which no other in-line citation is provided.
