10*10= 100
if 100 equals 1 side, then x = 4 sides
since there are 4 sides on a square you multiply 100 by 4
your answer is 400 units²

Answer:
Trial- 2 shows the conservation of momentum in a closed system.
Step-by-step explanation:
Given: Mass of balls are 
Conservation of momentum in a closed system occurs when momentum before collision is equal to momentum after collision.
- Let initial velocity of ball

- Initial velocity of ball

- Final velocity of ball

- Final velocity of ball

- Momentum before collision

- Momentum after collision

Now, According to conservation of momentum.
Momentum before collision = Momentum after collision

We will plug each trial to this equation.
Trial 1

Trial 2

Trial 3

Trial 4

We can see only Trial 2 satisfies the princple of conservation of momentum. That is momentum before collison should equal to momentum after collision.
option A is correct answer friend
Hey there!
3,562: 1, 2, 13, 26, 137, 274, 1781, 3562
15b: 1, 3, 5, 15, b
5b: 1, 5, b
☆ Not all of the terms have b in it so we know We can't have that as an answer. Only two of the numbers have b in it
The one you see most common would be the biggest/greatest common factor would be
