<h2>The answer you are looking for is 3 and 1/2</h2><h2>(or 7/2 or 3.5)</h2>
Step-by-step explanation:
<h2>plz mark as brainliest!!!</h2>
We have the following expression:
(27a ^ 3-1) / (9a ^ 2-6a + 1)
Rewriting we have:
(27a ^ 3-1) / (9a ^ 2-6a + 1)
(27a ^ 3-1) / ((3a-1) * (3a-1))
We exclude the values that make the denominator zero:
3a-1 = 0
a = 1/3
Answer:
a valid exclusion for the algebraic fraction is:
c. a ≠ 1/3
120km.
Speeds that are travelling towards each other may be added together since we are looking for a total distance traveled.
