Well 3 feet=1 yard
so the conversion factor is 3ft/1yd
so 12 yards converted to feet is 
12yd times 3ft/1yd
the yd will cancel and you will be left with 36 feet
each banner is 1 foot so 36/1=36
she can make 36 banners

Answer:
x=4
Step-by-step explanation:
9x-18 = x+14
9×-× = 14+18
8× = 32
X = 4
 
        
             
        
        
        
It is 18 because it is a square so all the sides have to be the same so that would make it 18
