(xiv) K = {x: x is an integer and - 3 < x < 5}
please please answer​

Answer 1

Answer:

(i) {17, 19, 21, 23, 25}

(ii) A = (C, H, I, T, A, M, B, R}

(iii) B = {16, 18, 20, 22, 24, 26}

(iv) P = {a, e, i}

(v) S = {0, 1, 4, 9, 16, 25, 36, 49}

(vi) {12, 18, 24; 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90}

(vii) C = {4, 6, 8, 9, 10, 12, 14, 15, 16, 18}

(viii) D = {2, 3, 5, 7, 11, 13, 17, 19,23}

(ix) E = {2, 4, 5, 6, 8, 10, 12, 14, 15, 16, 18, 20, 22, 24, 25, 26, 28}

(x) F={l,2, 3, 4, 6, 8, 12, 24}

(xi) G = {Triangle, quadrilateral, circle}

(xii) H = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

(xiii) 2x – 3 ≤ 17

⇒ 2x ≤ 17 + 3 2 x ≤ 20

⇒ x ≤ \frac { 20 }{ 2 }

x ≤ 10

∴ J = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

(xiv) ∵ – 3 < x < 5

∴ x lies between – 3 and 5

∴ K = {- 2, – 1, 0, 1, 2, 3, 4}
