Answer 6

sorry to say but this time u didnt get them right:(

Answer 7

:/ okay can u tell me how to do them and which answers are right ?

In the question all the terms are positive. but in ur answer there is a minus sign.

Answer 9

so it would be the last one ? (4y + 9)(x + 6)

Answer 10

(4y + 9)(x + 6) =4y*x+4y*6+9*x+9*6
=4xy+24y+9x+54
yup it is:)

Answer 11

(3b + 4x)(3a − 2) for the second one. i got the arrow in the wrong place lol

Answer 12

ya it is right:)

Answer 13

okay and for the last one ? i didnt really understand it at all.

Answer 14

5ab(x + 6) − 4(x + 6)
Let us assume that x+6=y for simplicity
then u will have
