Question

More algebra 2 help please

Answer 1

I think its either A or D

Answer 2

there's almost no actual statistics involved in this one, if you times a positive by a positive, you'll always get a positive answer
ie 3* 5 = 15
however 3 *-3 = -9
so there's no way you could have a negative number in your expansion

Answer 3

so the 2 probable answers are A or C

Answer 4

and nothing times 3 = 1, so C's out

Answer 5

Options B and C can be eliminated as 3^7 is not a 1
Choice D can be eliminated because of the negative signs. that doe not leave you with much of a choice does it?
