Using logarithmic function concepts, it is found that the correct statement is:
x = 9 is a true solution and x = -9 is an extraneous solution.
<h3>What is a logarithmic function?</h3>
A logarithmic function is modeled by:
It means that:
In this problem, we have that:
Applying the power property:
Applying the definition:
As the logarithm function is defined only for positive values, the correct statement is:

Answer:
There are 7 sides
Step-by-step explanation:
You can use the formula for finding the sum of the interior angles:
S=180(n−2) where n is the number of sides
If the sum is 900° we have:
180(n−2)=900
n−2=900/180
n−2=5
n=5+2=7
There are 7 sides.
