Step-by-step explanation:

Calculate the length of JK using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = J(1, 5) and (x₂, y₂ ) = K(3, 9)

JK =

    =

    =

    = ≈ 4.47 ( to 2 dec. places )

step-by-step explanation:

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
