  A (as marked)

Step-by-step explanation:

It often works well to eliminate the answer choices that can't be right.

The constant term of the sum must be ...

  -7 + 4 = -3 . . . . . eliminates choices B and D

The highest-degree term of the sum must be ...

  ( ) +(3x^2y^2) = 3x^2y^2 . . . . eliminates choice C

The remaining viable choice is A. Checking the sum term by term, you find A is the correct choice.

The only terms that combine are the xy^2 terms and the constants.

the circle one

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal
