Answer:
No, it cannot make a triangle
Answer:
b. The greater the number of independent variables measured, the more difficult it is to interpret higher-order interactions.
Answer:
If all four angles of a rectangle have the same measure, then it is a square.
Let a ∈ A. Then a is some integer that is divisible by 4, so we can write a = 4k for some integer k.
We can simultaneously rewrite a as a = 2•2k, so 2 clearly divides a, which means a ∈ B as well.
Therefore A ⊆ B.
