Answer:
n = ±6 .
Step-by-step explanation:
A quadratic equation is given to us and we need to find out the solution of the given equation . The given equation is ,
 
Subtracting 18 both sides ,
 
Multiplying both sides by -2 , 
 
On simplyfing , we get ,
 
Putting squareroot both sides ,
 
This equals to ,
 
<u>Hence</u><u> the</u><u> </u><u>value</u><u> of</u><u> </u><u>n </u><u>is </u><u>±</u><u>6</u><u> </u><u>.</u>
 
        
             
        
        
        
So you want to find the price for 1 apple you find that by dividing so 23.60/5=4.72
and 32.76/7=<span>4.68 
so, the 7 bag for 32.76 is the better deal</span>

Answer:
Step-by-step explanation:
5 + x - 12 = x- 7 (Add the 5 and -12 to simplify)
x - 7 = x - 7        (notice its the same on both sides of equal sign. Add 7 to both                    sides)
x = x 
solution is all real numbers
Part B 
5 - 4 - 12 = -4 - 7
-11 = -11
5 + 0 - 12 = 0 - 7
-7 = -7 
5 + 5 - 12 = 5 - 7
-2 = -2
