set {x : (x – 2)(x – 3) ≥ 0} is equal to

A. {x : 2 < x ≤ 3} B. {x : x ≤ 3} ∪ {x : x ≤ 2}
C. {x : x ≥ 3} ∪ {x : x ≤ 2} D. {x : x ≤ 3} ∪ {x : x ≥ 2}

Answer 1

Answer:

1 + 2 + 4 + 7 + 14 + 28. = 56 = 2(28). (iii) False. 7,747 is not a multiple of 37. Example 3 If X and Y are subsets of the universal set U, then show that. (i) Y ⊂ X ∪ Y.
