Prove that if a graph g has 11 vertices, then either g or its complement g must be nonplanar. (hint: determine the total number n11 of edges in a complete graph on 11 vertices; if the result were false and g and its complement were each planar, how many of the n11 edges could be in each of these two graphs? )

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

21

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
