Answer:
The correct answer is C. 
The factorization of 
 is (2x+3)(x+3).
 is (2x+3)(x+3).
Explanation:
The middle tiles represent 
 . This is because we have two
. This is because we have two 
 , 9 xs, and 9 ones. In order to get the factorization from the tiles we can simply look at the information on the outside of the box. On the top we can see 2 xs and 3 ones. This is the (2x+3). On the left we see 1 x and 3 ones. This is the (x+3).
