Answer: 7x + 3

Step-by-step explanation: To simplify, notice that there are two terms that contain an <em>x</em> in this problem and they are 2x and 7x.

Since both terms contain an <em>x</em>, you can add them together.

So 7x + 2x simplifies to 9x.

Now we have 7x + 3.

Now, you might think that 7x + 3 simplifies to 10x but that's not the case.

7x + 3 can actually not be simplified.

In order for you to be able to add two terms together, you need to have variables that are exactly the same.

A pile of coal is stored in a barrel-shaped bin whose base has a radius of 3 meters. the height of the pile measures 1.5 meters.
Aleksandr-060686 [28]

42.41 cubic meters    
The volume of a cylinder is bh where b is the area of the base and h is the height of the cylinder. And since the area of a circle is pi r^2, we have this equation for the volume of a cylinder  
V = pi*r^2*h    
Now substitute, the known values for r and h, then calculate the result:  
V = pi*r^2*h  
V = 3.14159*3^2*1.5  
V = 3.14159*9*1.5  
V = 42.411465  
V = 42.41   
 So the volume of the coal pile is 42.41 cubic meters.
