She should have added 2 to both sides of the equation instead of subtracting 2.

2x -2 = 14

Add 2 to both sides:

2x = 16

Divide both sides by 2:

Option D is correct.

$\triangle ADE \sim \triangle ABC$

Step-by-step explanation:

In triangle ADE and triangle ABC

From the figure:

$\angle ADE = \angle ABE$ [Angle] [Given]

Which shows one way to determine the factors of x^3 - 9x^2 + 5x - 45 by grouping ?

adoni [48]

You can group first two conjunctions and second two:
$x^3 - 9x^2 + 5x - 45=(x^3-9x^2)+(5x-45)$ .
In first brackets you have common $x^2$ and in second brackets common is 5:
$(x^3-9x^2)+(5x-45)=x^2(x-9)+5(x-9)=(x-9)(x^2+5)$ .
