Would have to be C due to all the other numbers not adding up to be a right angle
        
                    
             
        
        
        
Answer:
Hilda needs 64 ft² of tile
8601 in² will be uncovered post mounting
Step-by-step explanation:
Ar=10•6=60 ft²
At=[4•2]/2=8/2=4 ft²
total area=Ar+At=60+4=64ft²
......
Atv=31•57=1767 in²
Aw=(12•8)•(9•12)=10368 in²
Au=Aw-Atv=10368-1767=8601 in²
 
        
             
        
        
        
1.65
You can substitute in the values of p, n and e to get the equation:
5700 = 4000c - 900
add 900 to both sides and you get
6600 = 4000c
divide both sides by 4000 and you get
1.65 = c
so the answer is 1.65
