The inequality would look like this:
-2 (3x + 2)

-6x-4
To begin to find the solutions, distribute the -2 throughout the set of parenthesis on the left side of the inequality by multiplying the -2 by each term in the set of parenthesis
-2 x 3x = -6x
-2 x 2 = -4
-6x -4

-6x-4
Begin to isolate x by performing the opposite operation of adding -6x on both sides of the inequality
0x -4

-4
Next perform the opposite operation by adding 4 on both sides of the inequality
0x

0
Now, I'm not exactly understanding how that can possibly work. So, I guess I didn't really help you. But add a comment so that we can talk about the problem :)
Answer:

Step-by-step explanation:
If the complex number
is a root of a cubic function, then the complex number
is a root too. Thus, the cubic function has three known roots
and can be written as

Answer:
n = 21 degrees
Step-by-step explanation:
the second triangle is isosceles, so the angles of the base are congruent
a triangle have the sum of the interior angles equals to 180
n + n + 138 = 180
2n = 42
n = 21
