Answer:
180
Step-by-step explanation:
add 1% to 31.50 to get 31.815
then take the total 5276.70 and divide by 31.815
 
        
             
        
        
        
Distance=amount of gas times miles per gallon
distance=y
amount of gas=x
mpg=?
given
y=300
x=10
300=10 times ?
divide both sidesj by 10
30=?
equation is 
y=x times 30 or
y=30x
        
             
        
        
        
If he has 6 left over it  has to  be 288 cubic feet so the dimensions could be 12x12x2
        
             
        
        
        
When exponents are separated by a parenthesis it means you need to add them. Because the parenthesis is around the entire number then you raise everything inside the parenthesis to the outside exponent. Then anything raised by 0 as an exponent is automatically 1.
You think of this visually as 3a*3a*3a= 27a^9 is your answer
        
             
        
        
        
The answer would be 5x^3-2x^2=18
