Explanation:
The quadrilateral will be a parallelogram if the diagonals bisect each other. That is, their midpoints are the same point. We don't actually need to calculate the midpoint. Rather, we can calculate the point that has double the coordinate values.
If (A+C) = (B+D), the quadrilateral is a parallelogram.
A +C = B +D
(-2, 8) +(5, 1) = (2, 7) +(1, 2)
(-2+5, 8+1) = (2+1, 7+2)
(3, 9) = (3, 9) . . . . . the figure is a parallelogram
_____
Of course, the midpoint of the diagonals is (3/2, 9/2).

hello the answer is .04/0.04
Answer:
(x-4)² = 44
Step-by-step explanation:
To complete the square, take the middle term -8x and divide the coefficient in 2 and square it. Here it is -8/2 = -4. -4² = 16. Add 16 to both sides.
x² - 8x - 10 = 18
x² - 8x + 16 - 10 = 18 + 16
(x-4)² - 10 = 34
(x-4)² = 44
