Ans: C, {5}
*In set B and C, element 2 was repeated but not for set A.
6/10 and 5/10
The common denominator is 10
41.5 times 8.4 is the equation your in high school so you should know the rest
(-2-4y)(-8)
Use distributive property:
(-2*-8)+(-4y-8)
(remember that when 2 negative numbers are multiplied together it becomes positive.
16+32y
