Answer:
9, 10, 3y, 5, 3y, 5
Explanation:
First look at the second row
_(2y+3)+_(2y+3)
We know that if we multiply the first blank time 2y is should equal 6y^2, so the answer for the first one is 3y. The third blank times 3 should be 15, so the answer for the third one is 5. Therefore, 3y(2y+3)+5(2y+3).
Now if we distribute, we get the answer for the first part: 6y^2+9y+10y+15.
In the second line we got, 3y(2y+3)+5(2y+3), we can factor out the 2y+3 and end up with (2y+3)(2y+5).
