Could you with a algebra problem (unions and intersections)? got stuck on this ninth one.
construct the appropriate number sets with the given information. use the sets to match the following:
given
a = ø
b = b
c = then a ∪ b = b
d = a
e = then a ∩ b = b
1. if a union b
2. a union c
3. a intersect b
4 . a intersect c
5. b intersect c

What is the simplified expression for 6(2(y+x))

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2
