Answer:
x = -12
Step-by-step explanation:
2x^2 + 8 = x^2 - 16
2x + 2x + 8 = x + x - 16
4x + 8 = 2x - 16
-2x -2x
2x + 8 = -16
-8 -8
2x = -24
---- ------
2 2
x = -12
For this case we must divide the following expression:

The expression can not be simplified. When dividing we have that its decimal form is given by:
3,201550
If we convert to a mixed number we have:

Verifying:

Answer:

First you need to move that n over im fairly certain
Answer:
°
Step-by-step explanation:
For the upper left angle, we know that they are supplementary, so we can find the first angle of the triangle by

For the bottom right angle, we know that they are supplementary, so we can find that angle by

As a triangle has 180 degrees, we can subtract the values of the other two angles to find the final upper right angle.

Lastly, The upper right angle and x are supplementary so we can find x by subtracting the angle from 180
