Answer:
Option D. It's a perfect square trinomial.
Step-by-step explanation:
(a) 36x² - 4x + 16
= (6x)² - 2(2x) + (4)²
It's not a perfect square trinomial
(b) 16x² - 8x + 36
= (4x)² - 2x(4x) + (6)²
It's not a perfect square trinomial
(c) 25x² + 9x + 4
= (5x)² + 2
+ (2)²
It's not a perfect square trinomial
(d) 4x² + 20x + 25
= (2x)² + 2(10x) + (5)²
= (2x+5)²
It's a perfect square trinomial.

1) 3 groups
2) Animals that fly
3) 32 (? It’s blurry but the answer is the percentage in the blue part)
4) A cow would be classified in “animals that walk” and a whale would be classified in “animals that swim”
5) It would not be useful now because animals like frogs can do multiple things, in early stages it could swim but when it gets older it could live on land. (Sorry if 5 is not the best answer, but it’s how I’d answer it.)
