Question

Find the distance between the points (-4,-5) and (2,5)

Answer 1

`2 √(34)`

Explanation:

`\sqrt{(x2 - x1) {2}^{} } + √((y2 - y1))`

`\sqrt{(2 - ( - 4)) {}^(2) + (5 - ( - 5)) {}^(2) }`

`\sqrt{(2 + 4) { }{ {}^(2) + (5 + 5) {}^(2) } }`

`√(36 + 100)`

`√(136)`

`= 2 √(34)`

Answer 2

11.66

Explanation:

√(-4-2)²+(-5-5)²

√(36)+(100)

√136

11.66
