Answer:
14 and 42
Explanation:
To determine which numbers in set A are elements of both set B and set C, you need to identify the numbers that are both even and multiples of 7. Let's break it down:
Set B = {even numbers} = {-4, 2, 14, 34, 42}
Set C = {multiples of 7} = {-7, 14, 21, 42}
The numbers that are present in both set B and set C are 14 and 42. These two numbers are even (from set B) and also multiples of 7 (from set C). Therefore, the solution is:
So numbers in both Set B and Set C are 14 and 42.
