Answer: If the coordinates are D: (-2,3) and E: (-4.-5)
the distance between the coordinates is about 8.25
Explanation: Use the Pythagorean Theorem a² + b² = c²
Imagine a triangle formed on the grid of the graph with the difference in y values as the altitude, the difference in x-values as the base and c is the hypotenuse, the distance between the coordinates.
The difference in the y-values is 3 -(-5) = 8
The difference in the x-values is -2 -(-4) = 2
8² + 2² = c²
64 + 4 = 68 To find c, take the square root of c²
√68 = 8.246211251
Rounding to the nearest hundredths, that is 8.25
A. Is the answer to this question
Australia is an island country, and besides the big main island and Tasmania, it has 12,000 islands plus in its territory. Since it doesn't have any land borders, its borderline is actually the sum of all coastlines of all islands in its territory, and that accounts for 70,000 km.
New South Wales is the biggest state in the country, and it occupies 10% of its total land mass. Its border is 4,635 km, which means that it accounts for 6.62% of the total borderline of Australia.
