The answer to your question is:

Step-by-step explanation:

12.-

x² - 6x = 5

x² - 6x + (3)² = 5 + (3)²

x² - 6x + 9 = 5 + 9

(x - 3)² = 14

13.- x² - 6x = 12

x² - 6x + (3)² = 12 + (3)²

x² - 6x + 9 = 12 + 9

(x - 3)² = 21

x - 3 = ±√21

x1 = √21 + 3 x2 = -√21 + 3

x1 = 7.58 x2 = -1.58

14.- 2x² - 24x = - 20 Divide by 2

x² - 12 x = -10

x² - 12x + (6)² = - 10 + (6)²

x² - 12x + 36 = - 10 + 36

( x - 6) ² = 26

x - 6 = ±√26

x1 = √26 + 6 x2 = -√26 + 6

x1 = 11.1 x2 = 0.9

Solve for x 8/14=x/37

Setler79 [48]

Hello there!

$\frac{8}{14}=\frac{x}{37}$

Explanation:

↓↓↓↓↓↓↓↓↓↓↓

First you had to switch sides of the equation.

$\frac{x}{37}=\frac{8}{14}$

Then you had to cancel by the common factor of 2.

$\frac{x}{37}=\frac{4}{7}$

You had to multiply by 37 from both sides of the equation.

$\frac{37x}{37}=\frac{4*37}{7}$

Simplify it should be the correct answer.

$x=\frac{148}{7}$

<em><u>Answer⇒⇒⇒x=148/7 </u></em>

Hope this helps!
