20 because radius times height will give you the surface area of the shape
U={1,2,3,4,5,6,7,8,9} <br>
a={2,4,6,8} <br>
b={3,6,9} <br><br>
What is the set AUB?
ella [17]
Answer:
AUB = {2,3,4,6,8,9}
Step-by-step explanation:
The set u should not be included in set AUB
Answer:
(y-(-2))/(x-(-1)= (-2-4)/(-1-3)
(y+2)/(x+1)= (-6)/(-4)
(y+2)/(x+1)= (3/2)
Cross multiplying
2y+4= 3x+3
3x-2y-1=0
