It’s probably most definitely the third one but I really don’t know.
Answer:
Step-by-step explanation:
N is 3 bc #of terms minus 1
Exponents go from 3>2>x>none
Can be factored using binomial theorem
Answer:
A dilation of 2 about the origin.
Step-by-step explanation:
You can see in the original figure the points are half the points of the transformed figure.
For example the coordinates of H are (0.5,0)
The coordinates of H' are (1,0)
Since 0.5 * 2 = 1
There is a dilation of 2 about the origin.
The interior angles of a triangle add up to 180 degrees, meaning we can make an equation.



Hope this helps.
頑張って!
subtract 6 from the 21x+6. Then divide by 21. The answer is going to be -6/21
