Answer:
Here's a link that I found that was helpful to me: http://www.biology.arizona.edu/biomath/tutorials/quadratic/roots.html#:~:text=Roots%20are%20also%20called%20x%2Dintercepts%20or%20zeros.&text=The%20roots%20of%20a%20function,%2B%20bx%20%2B%20c%20%3D%200.

Answer:
3.67 units
Step-by-step explanation:
The central angle is at the point (0,0).
Then it's at the point (1,0)
Then it moved 210 degrees.
Let's bear in mind that we start moving the degree from it's current position.
So moving 210 degrees is moving 180 degrees plus 30 degrees.
Moving 180 degrees I like transforming linearly.
Now the location is at (-1,0)
But the distance covered will be
= 2πr*210/360
r = 1
= 2*3.142*1*(210/360)
= 6.144*0.5833333
= 3.67 units
There are no answer options so I will just simplify the expression:
3xy-(2x+4xy)
3xy-2x-4xy
-2x-xy
3+2•6/3
first you multiply the 2 and 6 on the top to get 12
so now it’s
3+12/3
now add the 12 and 3
15/3
now divide
so your answer is 5
That is maybe how and my teacher told me that if you have a whole number you can add a line underneath it
