Answer:

x= 2.5

Step-by-step explanation:

Simplifying

2x + -14 = -9

Reorder the terms:

-14 + 2x = -9

Solving

-14 + 2x = -9

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '14' to each side of the equation.

-14 + 14 + 2x = -9 + 14

Combine like terms: -14 + 14 = 0

0 + 2x = -9 + 14

2x = -9 + 14

Combine like terms: -9 + 14 = 5

2x = 5

Divide each side by '2'.

x = 2.5

Simplifying

x = 2.5

I think its C, not sure

Yes; you are correct.
___________________________________________________
The correct answer is:
___________________________________________________
Answer choice: [C]: " x³ − 9x² + 23x <span>− 12 " .
___________________________________________________
Note: (a </span>− b) (c − d + e) = ac − ad + ae − bc + bd − be ;
___________________________________________________
(x − 4) (x² <span>− 5x + 3) =

x * x</span>² = x³ <span>−

x * 5x = 5x</span>² +

x * 3 = 3x <span>−

4 * x</span>² = 4x² <span>−

-4 * 5x = -20x +

-4 * 3 = -12;
________________________________________
</span> (x − 4) (x² − 5x + 3) =

x³ − 5x² + 3x −4x² − (-20x) + (-12) ;

= x³ − 5x² + 3x −4x² + 20x − 12 ;

= x³ − 5x² − 4x² + 3x + 20x − 12 ;

= x³ − 9x² + 23x − 12 ; which is:
