It's a pattern, you add three to every row. (1st row) 6+3=9, (second row) 9+3=12, (third row) 12+3=15, (fourth row) 15+3=18, (fifth row) 18+3=21, (sixth row) 21+3=24, (seventh row) 24+3=27 (eighth row) 27+3=30.

Answer:

2.

4x^2 + 4 - 5x + x - 2x^2 + 8

= (4x^2 - 2x^2) + (x - 5x) + (4 + 8)

= 2x^2 - 4x + 12

=> D is correct

3.

2x^2 + 6x - 7x + 8 - 3x^2 + 1

= (2x^2 - 3x^2) + (6x - 7x) + (1 + 8)

= -x^2 - x + 9

=> C is correct

4.

B is correct (4 and 3)

Hope this helps!

:)
