Answer:

Step-by-step explanation:

Hello,

First of all we will take any real number x different from 0, -2, +2 as dividing by 0 is not allowed and then we can write

$\dfrac{( - x - 2)}{x(x^2 - 4)}=-\dfrac{x+2}{x(x-2)(x+2)}=\large \boxed{ -\dfrac{1}{x(x-2)}}$

because we know that

$x^2-4=x^2-2^2=(x-2)(x+2)$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

-2x + 4 = 3<br>how would you solve this problem?

ikadub [295]

-2x+4=3
move the 4

-2x+4=3
-4 -4

-2x=-1
then you would move the -2 by using division

-2x=-1
__ __
-2 -2

x=0.5

Solve the inequality. 1/3b - 4 ≤ 4

ladessa [460]

Answer:

b ≤ 24

Step-by-step explanation:

Treat it like a two-step equation:

1/3b - 4 ≤ 4

Add 4 on both sides: 1/3b - 4 (+4) ≤ 4 (+4)

1/3b ≤ 8

Multiply 3 on both sides (3)1/3b ≤ 8(3)

b ≤ 24
