Answer:
148.5 meters^3
Step-by-step explanation:
The volume of a rectangular prism can be found using the following formula. 
V=l*w*h 
The length is 6 meters. The height is 4.5 meters. The width is 5.5 meters. Substitute these values into the formula. 
V=6*5.5*4.5 
Multiply all the values together 
V=33*4.5
V=148.5 
Add appropriate units. Volume uses units^3 and the units are meters. 
V=148.5 meters^3 
The volume of the rectangular prism is 148.5 cubic meters. 
 
        
                    
             
        
        
        
 Answer:
Part A: 7n + 30= -5 and 8n + 40= 16
Part B: 7(8) + 30= 86 and 8(8) + 40= 104
Part C: Company A saves you 12.
Step-by-step explanation:
Company A: 7n + 30
Company B: 8n + 40
7n + 30= -5       8n + 40= 16
7(8) +30= 86     8(8) +40= 104
7(2) + 30= 44    8(2) + 40= 56
56 - 44= 12
 
        
             
        
        
        
Answer:
2x-12
Step-by-step explanation:
First you distribute the -2 to the x and +3 
this will make you expression be:
4x-6-2x-6
you then do -6+-6 
this will make your expression be:
4x-12-2x
After you get this you have to combine like terms. the like terms in the expression are the two with x being you variable. 4x and -2x.
Once you have combined like terms your solution should be:
2x-12
 
        
             
        
        
        
Hi!! What do you need help with? Solving the problems? Or understanding them? Also 1-9 is a bit blurry, so if you could retake it and repost it, I could solve for them. :). But if you don’t want to, don’t worry.
