Answer:
just add up all the squares. answer is 55
Step-by-step explanation:
X' = U - X
= {1,2,3,4,5,6} - {1,4,5}
= {2,3,6}
(ZUX') = {2,3,5} U {2,3,6}
= {2,3,5,6}
(Z⋃X′)⋂Y = {2,3,5,6} ⋂ {1,2}
= {2}
The answer is 91.
Since 2+2+2=6 and you subtract 2 that would now be 6-2, and that is 4.
87+4=91.
Simply 6-2=4
87+4=91
