Answer:

s=4

Step-by-step explanation:

3/4 s - 5/4 = s/8 +5/4

Multiply the equation by 8 to get rid of the fractions

8*(3/4 s - 5/4) =8( s/8 +5/4)

6s - 10 = s +10

Subtract s from each side

6s -s -10 s-s +10

5s -10 = 10

Add 10 to each side

5s-10+10 =10+10

5s= 20

Divide each side by 5

5s/5 = 20/5

s =4

Solve by completing the square<br><br> x^2-6x-16=0
Greeley [361]

Answer:

x = 8 or

x = -2

Step-by-step explanation:

<h2><em>Completing The Square</em><em>:</em></h2>

x² - 6x - 16 = 0

Here,

a = 1

b = -6

c = -16

Now,

x² - 6x + [6/2(1)]² - [6/2(1)]² - 16 = 0

x² - 6x + (6/2)² - (6/2)² - 16 = 0

x² - 6x + (3)² - (3)² - 16 = 0

(x - 3)² - 9 - 16 = 0

(x - 3)² - 25 = 0

(x - 3)² = 25

x - 3 = +-√25

x - 3 = +- 5

x = 3 +- 5

x = 3 + 5 or x = 3 - 5

<em><u>x = 8 or x = -2</u></em>

Hope it's helpful
