can you tell me the elements in C first?

Answer 4

2 4 6 8 10 12 14 16 18 20 22 24 = c

Answer 5

right...and for D?

Answer 6

uhh no idk

Answer 7

integers divisible by 6 from 1 to 30 so

D = {6,12,18,24,30}

got that?

Answer 8

mhmm

Answer 9

so C ∩ D is the set of numbers COMMON to both sets

Answer 10

the last one ?

Answer 11

right

Answer 12

{6, 12, 18, 24}

Answer 13

mmhmm
