Answer:

x = 16

Step-by-step explanation:

Corresponding sides are proportional.

BE/CD = AE/AD

20/(3x+8) = (x-1)/(x-1+27)

20(x+26) = (3x+8)(x -1)

In standard form, this is ...

3x^2 -15x -528 = 0

x^2 -5x -176 = 0 . . . . . . divide by 3

(x -16)(x +11) = 0 . . . . . . . factor

x = 16

This is the positive value that makes the product zero. x=-11 will also make the product 0, but gives negative segment lengths in the geometry. It is an extraneous solution.

Answer:

Step-by-step explanation:

-13 x 2 = -26

-4 x 2 = -8

14 x 2 = 28

-26 + -8 + 28 +-9 = -15

Need help with homework

We have two points describing the diameter of a circumference, these are:

$\begin{gathered} A=(-12,-4) \\ B=(-4,-10) \end{gathered}$

Recall that the equation for the standard form of a circle is:

$(x-h)^2+(y-k)^2=r^2$

Where (h,k) is the coordinate of the center of the circle, to find this coordinate, we find the midpoint of the diameter, that is, the midpoint between points A and B.

For this we use the following equation:

$M=(\frac{x_1+x_2_{}_{}}{2},\frac{y_1+y_2}{2})$

Now, we replace and solve:

$\begin{gathered} M=(\frac{-12+(-4)}{2},\frac{-4+(-10)}{2} \\ M=(\frac{-12-4}{2},\frac{-4-10}{2}) \\ M=(\frac{-16}{2},\frac{-14}{2}) \\ M=(-8,-7) \end{gathered}$

The center of the circle is (-8,-7), so:

$\begin{gathered} h=-8 \\ k=-7 \end{gathered}$

On the other hand, we must find the radius of the circle, remember that the radius of a circle goes from the center of the circumference to a point on its arc, for this we use the following equation:
