I don't get this. Help!! What does the difference of the means of each group indicate? What makes the mean of one group greater or less than the mean of the other group?

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

i would say true? if the unit was informational and it "refreshed your understanding", then true.

i think the answer is a.( -3, -1 )
