Multiplicity is how many times the root (or zero) is repeated
example, in
the root b has a multiplicity of n and the root d has a multiplicity of m
first we need to get the roots into
for (3x+5), we need to force factor out the 3 to get
factor the other one
but it is
which is equivilent to 
which simplifies to 
so we get
so the roots are -5/3 multiplicity 1 and 3 multiplicity 4
3 has a multilicity of 4

Answer:
<h2>The intensity of the sound is 3.16, approximately</h2>Step-by-step explanation:
The equation that determines decibel levels is
Where represents the intensity of the sound and the ten power represents the softest sound, that ratio is the comparison to find the decibels.
In this case, we have 125 decibels. So, we need to use this value in the formula to find the intensity
Therefore, the intensity of the sound is 3.16, approximately. Which is at the same level as a loud rock concert.
Answer: D) 3.75
Step-by-step explanation:
According to the Insersecting chords theorem, when you multiply the lengths of the segments of one of the chords in a circle, the product obtained is equal to the product of the segments of the other chord.
Based on this, you can find the value of "x" with:
Solve for "x" (Applying the Division property of equality, you can divide both sides of the equation by 4). Then:
This value matches with the option D.
