In a geometry class, students are asked to describe the dimensions of a plane based on the components that create a plane. Which student’s response is correct? Mark states that a plane has zero dimensions because it is made up of three noncollinear points. Stacy states that a plane has two dimensions because it is made up of an infinite number of lines. Dewayne states that a plane has one dimension because it contains the line intersecting two points. Candice states that a plane can have multiple dimensions depending on how many points are labeled.

Which of the following statements is true? a. the irrational number system is not closed under multiplication, because the product of two irrational numbers is always a rational number. b. the irrational number system is not closed under multiplication, because the product of two irrational numbers is not always an irrational number. c. the irrational number system is closed under multiplication, because the product of two irrational numbers is always an irrational number. d. the irrational number system is closed under multiplication, because the product of two irrational numbers is always a rational numbers. reset submit
