Somebody answer !!!!!

Rainbow [258]

Answer:

Step-by-step explanation:

First we have to subtract 5 from both sides

$\sqrt{x-6} +5=12\\\\\sqrt{x-6}+5-5=12-5\\\\\sqrt{x-6}=7$

Now, square both sides

$(\sqrt{x-6})^{2}=7^{2}$

x - 6 = 49

Now, add 6 to both sides

x - 6 +6 = 49 + 6

x = 55

Factor completely x3 − 6x2 − 5x + 30.

Lilit [14]

Answer:

Step-by-step explanation:

x³ - 6x² - 5x + 30 = x³ - 6x² - 5x + 5*6

Take x² from first two terms and (-5) from third & fourth term

= x²*(x - 6) - 5 (x - 6)

= (x - 6) (x² - 5 )
