that's not quite what their asking
Factors
like the factors of 18 are 1, 2, 3, 6, 9, 18
and the factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24

Answer 8

5(:

Answer 9

and then b would be five too?

Answer 10

correct! :)

Answer 11

okay thank you!(: what about 41?(:

Answer 12

associative property of multiplication (I think)
so it's just 2.1 * 10^8 * 4 * 10^5
and you can use commutative property to rearrange
(2.1 * 4) (10^8 * 10^5)

note that x^n * x^m = x^(n+m)
so like 10^3 * 10^6 = 10^(3+6) = 10^9

Answer 13

okay so it'd be d? (:

Answer 14

*squints*

8 + 5 = 13 right?
