Match each pair of points with the approximate distance between them. Round your answers to the nearest tenth. 7.07 units 5.1 units 2 units 2.83 units 5.39 units 13.15 units 12.5 units (3, -1) and (5, 4) (2, 3) and (4, 5) (-5, 7) and (8, 5) (-2, 4) and (3, -1)

(3, -1) -> (5, 4) = √29 or 5.38516

(2, 3) -> (4, 5) = 2√2 or 2.82843

(-5, 7) -> (8, 5) = √173 or 13.1529

(-2, 4) -> (3, -1) = 5√2 or 7.07107

Step-by-step explanation:

Distance Formula:

Simply plug the coordinates into the distance formula:

To get the decimals, we evaluate the square roots:

√29 = 5.38516

2√2 = 2.82843

√173 = 13.1529

5√2 = 7.07107

d = √[(x₂ - x₁)² + (y₂-y₁)²]

(3, -1) and (5, 4)

√(5−3)²+(4-(-1)²

√(2)²+(5)²

√4+25

√29 = 5.385164807134504 = 5.39

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
