Answer:
500 times
Step-by-step explanation:
They breathe 20 times per minute for 25 minutes
20(times per minute) x 25(minutes) = 500
The final displacement is 2cm in the right.
Given that the object begins from 0 and moves 3 cm towards the left side and then, 5 cm towards the right side.
The displacement is known as shortest distance between the initial and final positions.
Let the x-axis be the positive, +ve, and on the right side and negative -ve on the left side.
Thus, displacement would be:
D= 0 -3 +5
D= 2 cm
This implies that the object displaces 2cm towards the right side
Hence, the final displacement when object moves from 0 and 3 cm to the left and then 5 cm to the right is 2cm in the right side.

Answer:
Really does depend so i guess its D all of the choices
Combine like terms
a^2-4a^2=-3a^2
7a^3+11a^3=18a^3
Then put them back together from greatest exponent to smallest exponent
18^3-3a^2-a
