Answer:
its 84!
Step-by-step explanation:
volume of a rectangular prism is length * width * height, since the shape is 3D, or multi-demensional. you take all three numbers and multiply them together :) in this case its 7, 3, and 4. 4 * 3 is 12, and 12 * 7 is 84 :) 
 
        
             
        
        
        
The average rate of change of the function from x = 0 to x = 2 is -2
From the complete question (see attachment), we have the following ordered pair when x = 0 and x = 2

The average rate of change is calculated using:

So, we have:

Evaluate common terms

Divide -4 by 2

Hence, the average rate of change of the function from x = 0 to x = 2 is -2

30. 
3/4 is equal to 75%, so take 75% of 40 by multiplying .75 by 40 to get 30
