2(x-3)-8< -4 I need a explanation and the answer please.

Answer:

The solution to the inequality is:

$x$

The number line solution graph is also attached below.

Step-by-step explanation:

Given the inequality

$2(x-3)-8< -4$

Add 8 to both sides

$2\left(x-3\right)-8+8$

$2\left(x-3\right)$

Divide both sides by 2

$\frac{2\left(x-3\right)}{2}$

$x-3$

Add 3 to both sides

$x-3+3$

$x$

Thus, the solution to the inequality is:

$x$

The number line solution graph is also attached below.

(2n^4 - 8 - 3n) - (4n^2 + 7n +4) <br> I have to simplify but don't know how to

Ahat [919]

First remove the parenthes as there is a negtive outside the second parentheses the signs of the terms inside change.

= 2n^4 - 8 - 3n - 4n^2 - 7n - 4

Now simplify like terms

= 2n^4 - 4n^2 - 10n - 12

= 2(n^4 - 2n^2 - 5n - 6)
