Answer:
B. x < -4 and x > 3
Step-by-step explanation:
Factor and set = to 0
= 0
x = - 4 or x = 3 I call these critical values
The two numbers would divide a number line into 3 intervals. Pick a value in one of the intervals and put it in the original expression. If it makes the function positive, then all the values in that interval make the function positive. If the value you picked makes the function negative, then the values in the other intervals will make the function negative. Let's pick the value of 0 and substitute it into the function
We get + 0 - 12 = -12 which is not positive. Therefore, all the values between -4 and 3 will make the function negative. So, the values less than -4 or greater than 3 will make the function positive. Therefore, B is the correct answer.
Another way to do this problem is to graph the function and see where the graph is above the x-axis. But, sometimes it is not easy to graph the function.
Sum of interior angles = 180(n-2)
Where n= the number of sides in the polygon
A polygon is called a regular polygon when all of its sides are the same length and all of its angles are the same measure.<span>A </span>regular polygon is both equilateral and equiangular. <span>To find the </span><span>sum of its interior angles,</span> substitute <span>n = 5</span> into the formula <span>180(n - 2) </span>and get <span>180(5 - 2) = 180(3) = 540°</span>
<span>Since the pentagon is a </span>regular<span> pentagon, the measure of each interior angle will be the same.
To find the size of each angle, divide the sum, </span>540º, <span>by the </span>number<span> of </span>angles<span> in the pentagon.
(which is the same as the number of </span>sides).
<span><span>540° 5 = 108°</span>
</span>
There are 108° in each <span>interior angle of a regular pentagon.</span> N=8
(-3,-15) (-2,0) | (2,0) (3,15).
