Answer: ABCD is a parallelogram.
Step-by-step explanation:
First we plot these point on a graph as given in attachment.
From the attachment we can observe that AD || BC || x-axis .
also, AB ||CD, that will make ABCD a parallelogram , but to confirm we check the property of parallelogram "diagonals bisect each other" , i.e . "Mid point of both diagonals are equal".
Mid point of AC=
Mid point of BD=
Thus, Mid point of AC=Mid point of BD
i.e. diagonals bisect each other.
That means ABCD is a parallelogram.
Answer:
253,000
Step-by-step explanation:
- Plug the above answers in: 2.1 × 100,000 + 4.3 × 10,000
- 2.1 × 100,000 = 210,000
- Plug 210,000 in: 210,000 + 4.3 × 10,000
- 4.3 × 10,000 = 43,000
- Plug 43,000 in: 210,000 + 43,000
- 210,000 + 43,000 = 253,000
I hope this helps!
