Multiply and simplify
(x-4)(x^2 - 5x - 6)

x^3 - 9x^2 + 14x + 24

Step-by-step explanation:

(x-4)(x^2 - 5x - 6)

=x(x^2 - 5x - 6) - 4(x^2 - 5x - 6)

=x^3 - 5x^2 - 6x - 4x^2 + 20x + 24

=x^3 - 9x^2 + 14x + 24

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

a: inscribed angles
