Answer:
19 gallons
Step-by-step explanation:
Let x gallons be the amount of water which should be added to 6 gallons of pure acid in order to obtain the 24% acid solution.
Amount of water = x gallons
Amount of pure acid = 6 gallons
Amount of acid solution = x + 6 gallons
Amount of acid in acid solution = 24%
So, there are gallons of acid in acid solution.
Hence,
Solve this equation. Multiply it by 100:
We have been given the function
Convert this expression in difference of cubes form.
Now, in order to find the factors, we can apply the difference of cubes form, which is given by
On applying this formula, we get
Hence, the factors of the given expression are
Out of the given option, A is the correct option.
x^5 − 4 is the required factor.
