Answer 1

Do you know how to use the foil method?

Answer 2

Nope.

Answer 3

F.O.I.L

Answer 4

okay so you would first multiply the two first numbers in the equation 2X x 3X =?
then O. You multiply the outer numbers in the equation 2X x 4 =?
Then I. You multiply the inner numbers in the equation 5 x 3X=?
Then L. You multiply the last numbers in the equation 5 x 20=?

Now find an equation that would fit 2X x 3X, 2X x 4, 4 x 3X, and 5 x 20, which would be __________________________

Answer 5

sorry for the L i meant 5 x 4=20

Answer 6

Answer 8

Oh anyway I'd first solve the equation which is 6x^2+8X+15X+20.
Then I'd solve the multiple questions to see which one matches the equation a
