    I definitely agree with C for 9... I'm still thinking about 8.

    Do you have a calculator handy? If you do you can plug in sqrt(42) to see what that looks like.

    As a long way to the answer, here's what I am thinking:

    rational numbers are fractions... No way is sqrt(42) a fraction, it's decimals don't repeat.

    Because it's decimals don't repeat it is an irrational number for sure.

    Whole numbers are like 1, 2, 3, 4, and have no decimals.... so no to that.

    Integers are just whole numbers that are 0 or negative too, so -2, -1, 0, 1, 2, ... so no

    So, in other words, I think the answer is B. This is an irrational number because the decimals don't repeat.

    Yep, what a mess... definitely not a nice whole number, natural number, or integer.

    It is an irrational number. B Irrationals have nonrepeating decimals.
