Answer:
perimeter = 16x+9x+8x+11
simplified perimter = 33x+11
Step-by-step explanation:
this isnt even close to 100 pts but okay
 
        
                    
             
        
        
        
The cost of the meal multiplied by .19
        
             
        
        
        
Tot ratio=11
330/11=30
So Ed pay 7x30=210 
Fay pays 4x30=120
For Ed to give Fay money so they r equal, he would need to give $45 so that they both are at 165.
        
             
        
        
        
Let y = ax²+bx+c then substitute all of orders. we'll be doing equations system.

Ok we are at this.
Substitute c = 3 into equation 1 and equation 3.


then addition and subtract for a-b = 3 and a+b = -1

Therefore a = -2, substitute a = -2 in a-b+c=0 or a+b+c=2 but i'm doing a-b+c=0 one.

Therefore b = 1, substitute both a, b and c into y=ax²+bx+c as we get,
