Sovle for x . 4(x-4)=36

Katena32 [7]

Answer:

below

Step-by-step explanation:

$x.4 ( x-4) = 36 \\$

$4x(x-4) = 36 \\$

$4x^{2} - 16x = 36$

add -36 to both sides

$4x^{2} - 16x - 36 = 36 -36 \\4x^{2} -16x - 36 = 0$

divide both sides by 2

$\frac{4x^{2} - 16x - 36 }{4} = 0/4$

$x^{2} -4x-9 = 0$

This is a quadratic equation

let's solve it by graphing it

The solution are the x-coordinates of the intersection points

The x-coordinates of the intersection points are approximatively -1.6 and 5.6

The coordinates of point A are (-6, -10) and the coordinates of point B are (x,-4). The distance between A to point B is 10 unit

vlabodo [156]

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ A(\stackrel{x_1}{-6}~,~\stackrel{y_1}{-10})\qquad B(\stackrel{x_2}{x}~,~\stackrel{y_2}{-4})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ 10=\sqrt{[x-(-6)]^2+[-4-(-10)]^2}\implies 10=\sqrt{(x+6)^2+(-4+10)^2} \\\\\\ 10^2=(x+6)^2+(6)^2\implies 100=x^2+12x+36+36 \\\\\\ 100=x^2+12x+72\implies 0=x^2+12x-28 \\\\\\ 0=(x+14)(x-2)\implies x= \begin{cases} -14\\ \boxed{2} \end{cases}$

because B is on the IV Quadrant, the x-coordinate must be positive.
