Answer four questions in all. All questions carry equal marks.
h
(a)
If
U = {x CN; xẤ20}
A = {x: 1<x<10, where x is a composite number} B= {prime factors of 40},
C = {x: 1<x< 20, where x is a square number}
(i)
List the member of
a. A'UB
B. (A n B!) u C!
Y. (AluC)
8. U
(
ii)
Prove that union (u) is associative with respect to set A, B and C.
O

answer: 20

step-by-step explanation:

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
