Hey!!

Total angle - 180

... 2x + 4 + 2x - 9 + x = 180

... 4x - 5 + x = 180

... 5x - 5 = 180

... 5x = 185

... x = 185 / 5

... x = 37

Hope my answer helps!!

In simplest radical form, what are the solutions to the quadratic equation 0 = –3x2 – 4x + 5?

JulsSmile [24]

- 3 x² - 4 x + 5 = 0
$x_{1} = \frac{4+ \sqrt{16+60} }{-6} = \frac{4+8.718}{-6}$
x1 = -2.12
$x_{2} = \frac{4-8.718}{-6}$
x2= 0.786

If x varies directly with y and x = 3.5 when y = 14, find x when y = 18.

maks197457 [2]

Answer:

x = 4.5

Step-by-step explanation:

there's definitely other ways to solve this, but I used a proportion.

$\frac{3.5}{x} = \frac{14}{18}$

Then you can make this equation:

14x = 3.5 * 18

I solved for it and got 4.5 .
