will fan and medal 
Let A = {-3,-2,-1,0,1,2,3,}
Let B = {0,1,2,3,4,5}
Let C = {1,3,5,7,9}
Create a set that is equivalent to (A U B) n C

anonymous · Answer

first find $$A\cup B$$ i.e list all the stuff that is in those two sets

anonymous · Answer

it is a lot

anonymous · Answer

-3  -2  -1  0  1  2  3  0  1  2  3  4  5

anonymous · Answer

ok then once you have those, list all the stuff there that is also in C

anonymous · Answer

btw you shouldn't list stuff twice

anonymous · Answer

$$\{-3 , -2,  -1,  0,  1,  2 , 3,  0 , 1,  2,  3  ,4  ,5\}$$ is really $$\{-3,-2,-1,0,1,2,3,4,5\}$$

anonymous · Answer

OH okay thank you, so it would be {-3,-2,-1,0,1,3,5,7,9}

anonymous · Answer

no that is just $A\cup B$ not the final answer

anonymous · Answer

to find $(A\cup B)\cap C$ list all the stuff that is in common to $A\cup B$ and $C$

anonymous · Answer

But I added what was in C just didnt repeat the numbers the only diffrence is that B doesnt have 7 or 9
