Answer:
The given equation is NOT justified.
Step-by-step explanation:
Here, the given equation is 
= 
Now, here Consider the left hand side and simplifying the left side by operating on the like terms,
⇒ = 
=
Here, Left side of equation ≠ Right side of the equation
Hence, ≠
the songs are approximately 1 dollar each
80 songs times 1 dollar = 80 dollars
The sum of the infinite geometric series .. B.-1
To solve this problem you must apply the proccedure shown below:
1. You have the following expression:
<span>(5s/s^2-10s+25) - (25/s^2-10s+25)
2. As you can see, they have the same denominator, therefore, you can rewrite it as below:
(5s-25)/</span> (25/s^2-10s+25)
3. When you factor ir, you obtain:
5(s-25)/(s-5)(s-5)
3. Simplifying:
5/(s-5)
49. It has 3 or more factors.
