Answer:
your answer will be y-b because it is common in all the expression
The length is 10.
Since the two points share the same y-coordinate, the segment rt is horizontal.
This means that the length of the side is simply the difference (in absolute value) between the x coordinates of the two points.
So, we have

The answer should be
12t^2 - 14t
Let me know if it’s right.
It is side angle side postulate
fd is congruet to db
ed is congruent to da
and vertical angles theorem
The 0's keep adding up and up and up is q
