Answer 1

The first one seems to be the second choice.

Answer 2

Since a row of the block is x*1, a big square is x^2 and a little square represents just 1.

Answer 3

For the second and third problems, you just simplify alike terms.

Answer 4

-3f^2 + 4f - 3 + 8f^2 + 7f + 1 = (8-3)f^2 + (7+4)f -3 +1
= 5f^2 + 11f -2
So it is the third choice.

Answer 5

Try doing the last problem like this! :)
