Multiply the number by 4. Add 10 to the product. Divide this sum by 2. Subtract 5 from the quotient. The first number is 1 and the result is 2

The second number is 5 and the result is 10

the third number is 9 and the result is 18

the fourth number is 10 and the result is 20

Write a conjecture that relates the result of the process to the original number selected. part a)

Represent the original number as n.

Answer is 2n

part b Represent the original number as n, and use deductive reasoning to prove the conjecture in part (a). Multiply the number by 4.

Help with part b please.

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
