Answer:

C ∪ D={2,3,4,5, 9,10,11,12}

Step-by-step explanation:

If A = {x | x is an even integer}, B = {x | x is an odd integer}, C = {2, 3, 4, 5}, and D = {9, 10, 11, 12},

we need find the union of C  and D

For union combine all the elements of C and D. Write the repeated elements only once

C ∪ D={2,3,4,5, 9,10,11,12}

Here no elements are repeated

So C ∪ D={2,3,4,5, 9,10,11,12}
