A = (1, 3, 5, 7, 9, 11), B = {1, 2, 3, 4, 5, 6, 7) and C = (3, 6, 9, 12, 15) are the subsets of the universal set U = {1, 2, 3... 15). List the elements of the following set
operations and illustrate them in Venn-diagrams by shading.
a) A B C and A AuBuC complement

step-by-step explanation:

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

answer: 1 + 1 = 11
