The answer is option B. In the distributive property you need to multiply the constant that is outside of the parenthesis, with the terms that are inside :)
        
                    
             
        
        
        
Y=6 In this equation you also use combine like terms .
 
        
             
        
        
        
Let's represent the number of hours with the variable 'h' (or whatever letter you want it to be):
265 + 48h = 553
Substract both sides by 265:
48h = 288
Divide:
h = 6
6 hours of labor was spent
 
        
             
        
        
        
Answer:
40.3
Step-by-step explanation:
Use pythagoras theorem, a^2 + b^2 = c^2
400 + 1225 = 1625
sqrt of 1625 = approx 40.3
