Answer: OPTION 1
Step-by-step explanation:
For this exercise you need to remember that, by definition, the Arc length can be calculated with the following formula:

where "C" is the central angle of the arc in radians and "r" is the radius.
Since you need to find the Central angle, you have to solve for "C" from that formula, as following:

According to the information given in the exercise, you can identify that:

Therefore, the final step is to substitute these values into the formula and evaluate, in order to find the value of "C":

Answer:
The factored version of the given equation is going to be (3x² + 4y)(x + 5)
Step-by-step explanation:
<em>3x³ + 15x² + 4xy + 20y</em>
First, you break down 3x³. You can do this by finding the common factor of 3x³ and 15x². You can add the x to the other parentheses because x times x² equals x³
<em>(3x² + )(x + 5)</em>
Now, we break down 4xy by finding the common factor of 4xy and 20y.
<em>(3x² + 4y)(x + 5)</em>
So, the factored version of the equation above is (3x² + 4y)(x + 5)
