The <em><u>correct answers</u></em> are
A. Irrational numbers are nonterminating; and C. Irrational numbers are nonrepeating.
Explanation:
Irrational numbers are numbers that <em>cannot</em> be written as rational numbers, or fractions.
Terminating decimals have a specific endpoint; this means we can find the place value of the last digit of the number and write it as a fraction (if it ends in the tenths place, it is a fraction over 10; if it ends in the hundredths place, a fraction over 100; etc.).
Repeating decimals can also be written as a fraction; for example, 0.3 repeating is 1/3; 0.6 repeating is 2/3; 0.1 repeating is 1/9; etc.
This means that irrational numbers must be nonrepeating and nonterminating.
