Find the perimeter of quadrilateral (-1, 2) (2, 8), (6, 8) (3, 2). Round answer to nearest hundredth. 2 decimal places.
1 answer:
Answer:
21.42
Step-by-step explanation:
The length of the diagonal sides of this parallelogram are given by the distance formula:
d = √((x2-x1)^2 +(y2 -y1)^2) = √((2-(-1))^2 +(8-2)^2) = √(3^2 +6^2) = 3√5
Of course, the lengths of the horizontal segments are given by the difference in their x-coordinates: 3-(-1) = 4. As with any parallelogram, the perimeter is twice the sum of adjacent side lengths:
P = 2(d +4) = 2(3√5 +4) = 8 +6√5 ≈ 21.4164
P ≈ 21.42 units
The perimeter is about 21.42 units.

First, list the multiples of both numbers:
To find the lowest common multiple (LCM) of 6 and 8, first express the numbers as a product of its prime factors.
Next, pick the highest powers for each of the numbers:
Answer: This is a type of Synthesis reaction.
Explanation:
- Synthesis reaction is a type of chemical reaction in which two or more substances combine to form a single substance.
- Decomposition reactions are a type of chemical reactions in which a substance breaks down into two or more substances.
- Combustion reaction is a type of chemical reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide and water.
For the given reaction:
Here, 2 substances are combining together to form a single substance. Hence, it is considered as a synthesis reaction.
