G 2. (15 pt) Let X be a set with an equivalence relation ∼. Recall that, for an element x ∈ X, the equivalence class of x is the set [x] := {y ∈ X | x ∼ y} . a) Write down the precise definition of an equivalence relation. b) Using only this definition and the definition of equivalence class above, prove that for two elements s, t ∈ X, [s] = [t] if and only if s ∼ t.

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
