Answer: a = 18
explanation:
2(a + 10) = 56 -> distribute the 2
2a + 20 = 56 -> subtract 20 from both sides
2a = 56 - 20
2a = 36 -> divide both sides by 2
a = 18
Given A= {1,2,3,4,5,6,7,8,9} and B={2,4,6,8}, what is A U B?

A u B = { 1,2,3,4,5,6,7,8,9}
All elements of both sets , if they are repeating , you don't have to write them twice.
