You need the distance formula to figure this out. The coordinates for point D are (-5, 1), the coordinates for point E are (-2, 3), and the coordinates for point F are (-3, -2). For the distance or length of DE, the formula looks like this:
which simplifies a bit down to
which is
which of course is
so DE = 25. Moving on to EF:
which simplifies to
which is to say that
. We do the same for FD:
which simplifies a bit to
which is to say that the length of FD is
. None of the lengths of the sides are the same, so this is a scalene triangle. Last choice given above.
The area of a parallelogram is base times height. Each side can be a base, and has a particular height associated with it.
Here the height associated with the 1.5 base is 2.7, and the height associated with the 3.6 base is h. So
Answer: 1.125 units

Answer:
2(1g + 5h)
(2 x g) + (2 x 5h)
4g + 10h
_______
2
I don't know the options so I just did 3 possible ways it could be equal
X<-6 with the line under it is the answer, you would flip the sign when u divide
