Answer:
Circle
Step-by-step explanation:
This object is what we call "circle". All the points in the circle are at the same distance from a given point which is the center of the circle. Moreover, the distance between the center and every point on the circle is called "radius". Higher values for the radius imply points at a higher distance from the center.
Additionally, we can calculate the perimeter of the circle, or the circumference, with the following formula:
circumference = 2*(radius) pi
Where pi is an irrational number usually used as 3.14.
If you have doubts, try to draw a circle and measure the distance between the center and any point on the circle.
Answer:
Step-by-step explanation:
So the two lines before and after the expression means absolute value, or modulus of, knowing this, it means that the answer must always yield positive. So if x-6 is positive, it will stay positive, if x-6 is negative, it will turn positive, therefore it can never yield a negative value.
Now im assuming the second question is meant to be absolute value of x-5 is less than 0, because it makes no sense otherwise.
So now knowing that x-5 is always positive, or 0, but this inequality only wants less than 0, this means there are no solutions for the inequality.
2 would be the answer. Replace the x with the three and multiply that with the 2 and then subtract 4.
