Hey there!
Let's combine like terms!
First, let's write them together, like so:
-2.8d+2.8d-2.8d+2.8d-1.33+3.4-1.33
And now we can see that -2.8d and 2.8d cancel out:
-2.8d+2.8d-1.33+3.4-1.33
And they cancel out again:
-1.3+3.4-1.33
Now all we have to do is add the numbers together:
0.77
Hope it helps!
Answer:
The quadrilateral formed is a trapezoid
Step-by-step explanation:
In this case, it is necessary to know what points A, B, C, and D.
If the points are equal to the following coordinate points
A (-2, 1)
B (2, 1)
C (3, -2)
D (-3, -2)
As shown in the image the answer would be a trapezoid.
________________________________
The figure cannot be a square, a rhombus or a rectangle since by definition these are:
A square has all sides of equal length and all its right angles.
A rhombus is a parallelogram that has all sides of equal length and all its angles different from right angles.
A rectangle is a parallelogram that has all its right angles.
The figure that we obtain is neither a parallelogram nor does it have all its right angles.
