Solve x, this figure is a parallelogram, please show your work

Stels [109]

Answer:

x=4

Step-by-step explanation:

Since it's a parallelogram, the angle BCE(79) = angle CED(79)

so... 79+63 = 142

now...

142+8x+6=180(sum of angles in a triangle)

148+8x=180

8x=32

x=4

What is the solution of the equation when solved over the complex numbers?

kumpel [21]

Answer:

$x=+i\sqrt{20}\approx+4.472i$

$x=-i\sqrt{20}\approx-4.472i$

Step-by-step explanation:

Starting from $x^2+20=0$ , we do $x^2=-20$ , which means $x=\pm\sqrt{-20}$ , which can be written as $x=\pm\sqrt{(-1)(20)}$ , which gives us $x=\pm\sqrt{(-1)}\sqrt{(20)}$ , which we know is $x=\pm i \sqrt{(20)}$ , so our solutions are:

$x=+i\sqrt{(20)}$

$x=-i\sqrt{(20)}$

Which can be approximated to:

$x\approx+4.472i$

$x\approx-4.472i$

Answer:

Slope = ⅓ Y-intercept = -2

Step-by-step explanation:

by transforming the equation to y= ⅓x -2

then it becomes Y= ⅓x +(-2)

then you should get m= ⅓ and b = -2
