Answer:
The solutions will contain an infinite amount of negative numbers.
Step-by-step explanation:
Given x < 0
What does this mean?
First, carefully examine the sign in the inequality. It says less (which is different from less and equal)
Then explain it's meaning.
x < 0 just means that the solutions will contain an infinite amount of negative numbers but NOT zero. This defines the correct answer.
Answer:
X = -7

Answer:
389.1 units² (nearest tenth)
Step-by-step explanation:
<u>Regular polygon</u>: all side lengths are equal, all interior angles are equal.
<u>Apothem</u>: a line drawn from the center of any polygon to the midpoint of one of the sides
<u>Radius</u>: a line drawn from the center of the polygon to a vertex.
Therefore, we have been given the apothem of this regular dodecagon.
<h3><u>Formulae</u></h3>
where:
- n = number of sides
- l = length of one side
- a = apothem (the line drawn from the center of any polygon to the midpoint of one of the sides)
where:
- l = length of one side
- n = number of sides
<h3><u>Solution</u></h3>
First, calculate the length of one side of the regular dodecagon by substituting a = 11 and n = 12 into the apothem formula:
Now substitute n = 12, the found value of l, and a = 11 into the area formula:
