What is x in the similar triangles? Please help:)

topjm [15]

Answer:

x = 18

Step-by-step explanation:

Since both right triangles are similar, therefore:

$\frac{2x - 6}{20} = \frac{39}{x + 8}$

Cross multiply

$(2x - 6)(x + 8) = 39*20$

$2x(x + 8) -6(x + 8) = 780$

$2x^2 + 16x - 6x - 48 = 780$

$2x^2 + 10x - 48 = 780$

Subtract 780 from both sides

$2x^2 + 10x - 48 - 780 = 0$

$2x^2 + 10x - 828 = 0$

$2x^2 + 46x - 36x - 828 = 0$

$2x(x + 23) - 36(x + 23) = 0$

$(x + 23)(2x - 36) = 0$

x + 23 = 0

x = -23

Or

2x - 36 = 0

2x = 36

x = 18

Keep getting this wrong

Remember that the y-intercept is where the function has a value of $x = 0$ and the x-intercept is where the function has a value of $y = 0$ . Thus, to find the x-intercept and y-intercept, we can substitute these values into the equation and solve for the other variable.

<u>x-intercept</u>

Since the x-intecept has a y-value of 0, we can substitute this into the function and solve for $x$ .

$0 = -2x - 3$

Set up

$3 = -2x$

Add 3 to both sides

$x = - \dfrac{3}{2}$

Divide both sides by -2

The x-value of the x-intercept is $-\frac{3}{2}$ and the y-value is 0, meaning that the x-intercept has coordinates $\boxed{(-\frac{3}{2}, 0)}$ .

<u>y-intercept</u>

Since the y-intercept has a x-value of 0, we can substitute this into the equation and solve for $y$ :

$y = -2(0) - 3$

Set up

$y = -3$

Multiply and simplify

The y-value of the y-intercept is -3, meaning that the y-intercept of the function is $\boxed{(0, -3)}$ .
