Dollars per gallon where the dependent quantity is the dollars.
<span>
A </span>dependent<span> variable is a variable that represents a </span>quantity<span> that changes based on other </span>quantities<span> being manipulated in an experiment.</span>
3m/2n*n^3/6
= (m*n^3)/ 4n
= mn^2/4
The final answer is mn^2/4~
To factor out completely, we should have reached the most simplified form,
first we should take out 2.
2(x2 - 3x - 18)
then we should factor out the inside of the parenthesis,
2(x - 6)(x + 3)
And that's the most simplified and factored out form.
The final answer is then the second option, <span>2(x − 6)(x + 3)</span>
