Consider U = {x|x is a negative real number}.Which is an empty set?

The diagram shows the universal set U = {parallelograms}.Set A represents parallelograms with four congruent sides, while B represents parallelograms with four congruent angles.

Consider the following sets.U = {all real number points on a number line}A = {solutions to the inequality 3x + 4 ≥ 13}B = {solutions to the inequality x + 3 ≤ 4}For which values of x is A ⋃ B = Ø?

In the Venn diagram, consider U = {whole numbers 1 – 100}.Let A represent numbers that are perfect squares, B represent numbers that are perfect cubes, and C represent numbers that are perfect fourths, or numbers with a fourth root that is an integer.
