Answer 1

Answer:

x =9

Step-by-step explanation:

A $\cup$ B =29

-->A = 29 -17 = 12

-->B = 29 -21 = 8

x=A $\cap$ B =A $\cup$ B - A - B= 29 - 12 - 8 = 9

Answer 2

So to find x, you have to add both A and B which is 38. Since AuB (excluding the overlap) is 29, subtract 38 from 29 and you get 9 for x.
