Answer:
1
Step-by-step explanation:
You "complete the square" by adding the square of half the x-term coefficient. Here, that is ...
((-2)/2)² = 1 . . . . value added to complete the square
If you want to keep 0 on the right, you must also subtract this value:
x² -2x -36 = 0
x² -2x +1 -36 -1 = 0 . . . . . . add and subtract 1 on the left
(x -1)² -37 = 0 . . . . . . . . . . . written as a square

Answer:
- PQRS - a parallelogram
- GHJI - not necessarily
- RSUT - a parallelogram
- ABDC - a parallelogram
Step-by-step explanation:
A parallelogram has these characteristics that can be useful for answering this question:
- opposite sides are the same length
- opposite sides are parallel
- the diagonals bisect each other
__
<h3>PQRS</h3>
Opposite sides are the same length: a parallelogram
__
<h3>GHJI</h3>
Two isosceles triangles share a base segment. Not necessarily a parallelogram.
__
<h3>RSUT</h3>
The diagonals bisect each other: a parallelogram
__
<h3>ABDC</h3>
Opposite sides are parallel: a parallelogram. We know BD║AC from the converse of the alternate interior angles theorem. AB and CD are marked parallel.
That would be 1^2 + 20 , 2^2 + 20 and 3^2 + 20 (replacing n by 1 , 2 and 3)
