2 answers:
Answer:
Option: B is the correct answer.
B)
Step-by-step explanation:
We are given an algebraic expression in terms of the variable 'x' and 'y' as:
Now we are asked to find the expression that is equivalent to the above expression.
We could clearly observe that each of the term in the expression has a common term as:
Hence, we take out common this common term and write the remaining expression in bracket as:

Rotation being a rigid transformation, does not alter the angle and side lengths after transformation.
The arrow in Figure B will have the same angle measure as Figure A
From the complete question (see attachment), we understand that:
Figure A is rotated 90 degrees clockwise around point (2,2)
Rotation is a rigid transformation
This means that: after the transformation
- Figure A and figure B will have the same side lengths
- Figure A and figure B will have the same measure of angles
The above highlights imply that, the arrow in Figure B will have the same angle measure as Figure A
