Answer 1

Answer:

{7,8,9}

Step-by-step explanation:

A = {6,7,8,9}, B = {4,6,8,10}. [Given]

C = {x | x belongs to the set of Naturals and 2<x<=7}

Thus C = {3,4,5,6,7}.

B Union C = Set of common elements of B and C

Common elements are 4 and 6.

Thus B Union C = {4,6}

A - {4,6}

= Set A without elements of {4,6}

As 4 is not in A, we will ignore it.

Set A - {6} = {7,8,9}.
