Answer:
Step-by-step explanation:
lets have one side =a
P=3a+a+(17+a)=52
P=5a+17=52
5a=52-17
5a=35
a=7
second side=21
third side=24
 
        
             
        
        
        
Answer:
285.12
Step-by-step explanation:
discount amount = 45/100 x 480= 45x48/10
=216.0
price after discount= 480-216=264
sales tax= 8/100 x 264=21.12
total money spent = 264+21.12=285.12
 
        
                    
             
        
        
        
using the distributive property:
-4x + 20 + 3a - 21
Then combine like terms:
-4x + 3a - 1
A is the answer
