Answer:

d=√(193)

Step-by-step explanation:

d=√((x_2-x_1)²+(y_2-y_1)²)

Points: (9, 2) & (-3, 9)

d=√((-3 - 9)²+(9 - 2)²)

d=√((-12)²+(7)²)

d=√(144)+(49)

d=√(193)

Answer:

≈ 13.9

Step-by-step explanation:

Calculate the distance d using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = K(9, 2) and (x₂, y₂ ) = L(- 3, 9)

d = \sqrt{(-3-9)^2+(9-2)^2}

   = \sqrt{(-12)^2+7^2}

   = \sqrt{144+49}

   = \sqrt{193}

   ≈ 13.9 ( to the nearest tenth )
