Answer:


Step-by-step explanation:

1) (x-3),(x-8)

2) 3x^3+3x^2=27x

3 ( x 3^3+ x ^2 − 9 x − 9 )

3 ( x ^2 ( x + 1 ) − 9 ( x + 1 ) )

3 ( ( x + 1)( x ^2 − 9 ) )

3 ( ( x + 1 ) ( x ^2 − 3 ^2 ) )

3 ( x + 1 ) ( x + 3 ) ( x − 3 )

I will mark you brainiest if you can answer this <br> 12 - 13 x ≥38
Shtirlitz [24]
<h3><u>Explanation</u></h3>
  • Given Inequality

12 - 13x \geqslant 38

  • Solve the Inequality for x-term by making x as the subject.

Solving Inequality is almost the same as solving the equation.

- 13x \geqslant 38 - 12 \\  - 13x \geqslant 26

The problem is here. Some people might forget that when we move the negative coefficient to another side, we have to flip/swap or change the sign to opposite. That means we have to change from >= to <=

x \leqslant  \frac{26}{ - 13}  \\ x \leqslant  - 2

  • Answer Check by substituting x = -2 in the Inequality.

12 - 13( - 2) \geqslant 38 \\ 12 + 26 \geqslant 38 \\ 38 \geqslant 38

The Inequality is true for x = -2 and that means it is also true when x is lesser than - 2.

  • Substitute x = -3

12 - 13( - 3) \geqslant 38 \\ 12 + 39 \geqslant 38 \\ 51 \geqslant 38

Notice that if we substitute the number that are lesser or equal to -2, the Inequality will be true.

<h3><u>Answer</u></h3>

<u>\large  \boxed{x \leqslant  - 2}</u>
