Answer:
Option D.75°
Step-by-step explanation:
we know that
The sum of the interior angles of a regular dodecagon is equal to

where
n is the number of sides
In this problem
n=12 sides
substitute


Find the measure of each interior angle
Divide the sum of the interior angles by the number of sides

The measure of the angle formed by the radius and the side of a regular dodecagon is half the measure of the interior angle
therefore

(-3)^2 -4(-3) + 3
9 + 12 + 3
So the answer is 24

We can factorise this expression by grouping. First let us arrange it in this way

Let us bracket them like this:

In the first bracket portion, take x as common and in the second expression, take 2 as common.

Answer:
A. -½
Step-by-step explanation:
In the Slope-Intercept Formula, <em>y = mx + b</em><em>,</em><em> </em><em>m</em><em> </em>represents the <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>], so in this case, the slope is -½.
