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

If you turn the years into months(60) and multiply it by the 180 per month =, you end with 10,800 then multiply that by .49 because its a percent and get a total of 5,292. Finally add the 10,800 and 5,292 and the answer is $16,092.
