Answer:
B
Step-by-step explanation:
Factorize both quadratic polynomials, as shown below

Similarly,

Thus,

Therefore, since the denominator cannot be equal to zero.
<h2>The variable restrictions for the original expression are a≠-1,-4</h2>
Then, provided that a is different than -1,

<h2>The rational expression in the lowest terms is (x-4)/(x+4)</h2>
Answer:a
Step-by-step explanation:
Answer:3.25 gallons
