Answer:
2x - 9
Step-by-step explanation:
7x - (9 + 5x) < distribute the - into the parentheses to get rid of them
7x - 9 - 5x < combine like terms
7x - 5x = 2x
-9 stays as it is as there are no other terms to combine it with
the answer is 2x - 9
 
        
                    
             
        
        
        
Answer:
7 feets 
Step-by-step explanation:
Volume of shed, V = 357 feet³
Height of shed, H= 8 1/2 fts
Width of shed, W = 6 ft
Using the relation :
Volume = Length * width * height
357 = L * 6 ft * 17/2 feets
357 feets³ = L * 51 feets²
L = 357 feets³ / 51 feets²
Length, L = 7 feets
