Answer:
The fourth vertex is D(8, 0)
Step-by-step explanation:
Let A(0, 0), B(2, 4), and C(10, 4) be the three vertices of a parallelogram ABCD and let its fourth vertex be D(a, b).
Join AC and BD. Let AC and BD intersect at point O.
- We have known that the diagonals of a parallelogram bisect each other.
So, O would be the midpoint of AC as well as that of BD.


The midpoint of AC is:




The midpoint of BD is:

so
∵ 


∵ 


Hence, the fourth vertex is D(8, 0)
Answer:
Step-by-step explanation:
Remark
I take it that 24 is in front of j which means that the term is 24j. There shouldn't be a comma there.
Both numbers have 8 in common, and that's all they have in common. The GCF is therefore, 8
24j - 16 = 8(3j - 2) That's the answer.
Answer: 8 (3j - 2)
The value of 28 tens is 280 because a ten is literally 10 you only multiply 28*10= 280 So the value of 28 tens is 280.
Thank You!
Answer:
c = 29.5 or
c = 59/2
Step-by-step explanation:
2 (4 + c) = 67
8 + 2c = 67
8 - 8 + 2c = 67 - 8
2c = 59
c = 29.5
