PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!

Answer: x < -4 and -4 > x

x < -4 would be one of the two options.

This means that any number less than -4 is a solution.

This is shown by drawing an open dot on -4 and then

drawing an arrow to the left shows all answer less tan 4.

-4 > x would be our second option.

We can change it to say x < -4.

All I did was changed the order of numbers and switched the sign.

So x < -4 is the same as the first option.

Factorise : 64a cube minus 27b cube minus 144a square b plus 108ab square .

Svetlanka [38]

Answer:

$16a(4a^2-9a)+27b^2(4a-b)$

Step-by-step explanation:

The question is not properly formatted, here is a good format for proper understanding and readability

$64a^3-27b^3-144a^2+108ab^2$

let us first collect/ group like terms

$64a^3-144a^2+108ab^2-27b^3$

we can now bring out the common factors we have

$16a(4a^2-9a)+27b^2(4a-b)$

<em>The simplified expression is </em>

$16a(4a^2-9a)+27b^2(4a-b)$
