$\rm -3x+2-6x^2+13x-6= \\ \\ -6x^2+10x-4= -(6x^2-10x+4) \\ \\ 
6x^2-6x-4x+4=6x(x-1)-4(x-1)=(6x-4)(x-1) \\ \\ So~the~answer~is~\bold{-2[(3x-2)(x-1)]}$

- 3x + 2 ( - 6x² + 13x - 6 )
= - 3x - 12x² + 26x - 12
= - 12x² + 23x - 12

Find the slope of the line passing through the points (-5,3) and (-7,5).

Alekssandra [29.7K]

Step-by-step explanation:

points (-7,5) and (5,-3)?

This would mean to subtract the y coordinates:

5 - (-3) = 8

Then subtract the x coordinates in the same order:

-7 - 5 = -12

Then divide the y result by the x result for the slope:

8/-12 is the slope.

In simplest form, this is equivalent to -2/3

1. S = 10 mm V= S×S×S =___×___×___ =____ mm3

Minchanka [31]

Hi there!

»»————-　★　————-««

I believe your answer is:

$V=1000\text{mm}^3$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

I am assuming by the infomation given that the figure is a cube.

⸻⸻⸻⸻

$\boxed{\text{Finding the volume of the cube...}}\\\\S = 10mm; V= s^3\\--------------\\\rightarrow V = 10^3\\\\\rightarrow V = 10 * 10 * 10\\\\\rightarrow \boxed{V=1000\text{mm}^3}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
