What is the distance between (9,-4) and (-22, 8)?

≈ 33.2 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d =

with (x₁, y₁ ) = (9, - 4) and (x₂, y₂ ) = (- 22, 8)

d =

   =

   =

    = ≈ 33.2 ( to 1 dec. place )

a

explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
