(2x-5y) + (x+y)
= (2x+x) + (-5y+y)
= 3x + (-4y)
= 3x-4y
So option A is the correct one.
Answer:
e=mc
Step-by-step explanation:
The ice cube tray can make 200.96 cubic centimeters of ice.
<h3>
How to get the total volume?</h3>
For a sphere of radius R, the volume is:
![V = \frac{4}{3}*3.14*R^3](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B4%7D%7B3%7D%2A3.14%2AR%5E3)
In this case, we have 6 spheres, each one with a radius of 2cm.
Then the total volume of ice that the ice cube tray can make at one time is:
![volume = 6*V = 6*(\frac{4}{3} *3.14*(2cm)^3) = 200.96cm^3](https://tex.z-dn.net/?f=volume%20%3D%206%2AV%20%3D%206%2A%28%5Cfrac%7B4%7D%7B3%7D%20%2A3.14%2A%282cm%29%5E3%29%20%3D%20200.96cm%5E3)
The ice cube tray can make 200.96 cubic centimeters of ice.
