Question

I need help again :/

Answer 1

They have a zero in the ones place.

Explanation:

The first one, A., is not always true.

10 * 3 = 30

This does have a a three in the ones place, but watch when we multiply it again.

10 * 30 = 300

Now, it's not true.

B. does not make sense because they would always be an ever number, an d never odd.

C does not make sense either, because they're never odd numbers.

This leaves D, to be the right answer.

Answer 2

They have a 0 in the ones place

Explanation:

Because you start with 10, you will always have a 0 at the end.

30, 90, 270, etc.
