W to the fourth power is different than to the second power. So if you combine like terms which is 5w to the fourth power and -25w to the fourth power to get you to -20w to the fourth power and then add the 30w to the second power so that is -20w to the fourth power plus 30w to the fourth power.

How do I do this?<br> 4/5x&gt;14
Likurg_2 [28]

Well, first, you need to know what you want to 'do' to it.

You want to find the description of what 'x' has to be in order to
make that inequality a true statement.  Here's one way to do it:

                                              4/5 x > 14

Multiply each side by  5 :     4    x  >  70

Divide each side by  4 :             x  >  17.5 .

That's it.  As long as 'x' is more than 17.5 ,
the original inequality is true.

Which number line represents the solution |2x|-12 =
Bond [772]

Answer:

Third option, last one

Step-by-step explanation:

Let's solve for x first.

|2x| - 12 = -2

|2x| = 10

2x = 10 or -2x = 10

x = 5 or x = -5

The number line that represents this is the last one.
