I believe this is right. But not 100%
        
             
        
        
        
2x + 10...the common number between these 2 terms is 2...so factor the 2 out
2(x + 5) <==
        
             
        
        
        
37 to the nearest tenth is 40.
        
                    
             
        
        
        
Given:
Four equations in the options.
To find:
The equation which represents a proportional relationship.
Solution:
If y is proportional to x, then


where, k is the constant of proportionality.
In this case if x=0, then y=0. It means the graph of a proportional relationship passes through the origin.
From the given options, only option B, i.e.,  , is of the
, is of the  , where,
, where,  .
.
So, the equation  represents a proportional relationship.
 represents a proportional relationship.
Therefore, the correct option is B.
 
        
             
        
        
        
Answer:
250ft
Step-by-step explanation:
45ft + 45ft of fencing for the two short ends. 80ft +80ft for the two long sides 
45ft+45ft=90ft
80ft+80ft=160ft
90ft+160ft=250ft
