any ideas?

anonymous · Answer

i remember doing this but i cant remember how to teach it or do it if that makes any sense and i know u wernt talking to me @amistre64

anonymous · Answer

um no

anonymous · Answer

would i need an equation in this case

amistre64 · Answer

not really ... youd simply need to know:  what an even number is, what a number that is divisible by 5 is, and what a union is

amistre64 · Answer

which of these need to knows are giving you an issue?

anonymous · Answer

i think it is the second response @amistre64

amistre64 · Answer

hmm, i dont agree, but can you tell me why you thought it was B?  that way we can correct the mistake.

amistre64 · Answer

im thinking that you know what an even number is;  and what a number divisible by 5 is ... but that you cant recall clearly what a union of the sets give us

amistre64 · Answer

when i think of a union, i picture having a bag of m&ms and a bag of skittles .... we unite them unto the same bowl by pouring them both into the same bowl.  A union gives us all the elements of both sets together.

amistre64 · Answer

so, we want a union of the sets:

{2,4,6,8,10,12}  U  {5,10}

anonymous · Answer

So union would be the last response.

amistre64 · Answer

correct
