Answer:

D

Step-by-step explanation:

4x^2 gets simplified into 16x^2, 20x gets simplified into 400x, and 25 is just 25. 16 plus 400 equals 416, and 416 plus 25 equals 441. Divide 441 by 4, and you get 110.25, and then divide 110.25 by 4, which gives you ~27. D is the only choice that equals 27, so D is the answer. Hope this helps! :D
