Prove the following: let a , a, b , b, and c c be sets. if a ⊆ b a⊆b and b ⊆ c , b⊆c, then a ⊆ c . a⊆c. let a a and b b be sets. then a − b = a ∩ b c a−b=a∩bc . let a , b , and c a, b, and c be sets. if ( a ⊆ b a⊆b and a ⊆ c a⊆c) then a ⊆ b ∩ c . a⊆b∩c. let a and b a and b be sets. a ⊆ b a⊆b if and only if b c ⊆ a c bc⊆ac . let a , b , and c a, b, and c be sets. if a ⊆ b a⊆b then a × c ⊆ b × c .
