Tolong bantu ya plis

1. A = {1,2,3,4,5,6,7,8,9}

  B = {3,5,7,9,11,13,15}

  C = {2}

  D = {1,2,3,4,5,6,7,8,9}

  E = {-2,-1,0,1,2,3,4,5,6,7,8,9,10,11,12}

  F = {0,1,2,3,4,5,6,7,8,9}

2. a. A = {x | x < 30, habis dibagi 3, x ∈ bilangan ganjil}

   b. A = {3,9,15,21,27}

3. 1. P = {1,2,3,4,5,6,7,8,9},  P = {x | x < 10, x ∈ bilangan asli}

 2. K = {Bilangan prima yang kurang dari 14}, K = {x | x < 14, x ∈ bilangan prima}

 3. L = {-4,-3,-2,-1,0,1,2,3,4}, L = {bilangan bulat antara -5 dan 5}

 4. M = {3,5,7,9,11,13,15}, M = {x | x < 16, x ∈ bilangan asli ganjil}

 5. N = {4,5,6,7,8,9,10,11,12} , N = {bilangan asli antara 3 dan 13}

 6. O = {faktor dari 24} , O = {x | x faktor 24}

nomor 3 nomor 7 dan 8 aku nggak bisa, maaf ya

semoga jawaban yang diatas bermanfaat maaf kalo ada salahnya
