Complete the square to factor X^2 +10X=-8
ella [17]

Answer: x=\sqrt{17}-5 and x = -\sqrt{17}-5

Step-by-step explanation:

Alright, lets get started.

The given equation is :

x^{2} +10x = -8

Adding 8 in both sides, it will become

x^{2} +10x + 8 = -8 +8

x^{2} +10x + 8 = 0

To make it perfect square, we need to add 25 and subtract 25

x^{2} +10x + 8 +25-25= 0

x^2+10x+25+8-25=0

(x+5)^2+8-25=0

(x+5)^2-17=0

Adding 17 in both sides  

(x+5)^2=17  

taking square root

x+5=\sqrt{17}

So,

x=\sqrt{17}-5 and x = -\sqrt{17}-5  .. Answer

Hope it will help :)

Sinister Stan stole 3 3/4 oz of slime from Messy Molly, but his evil plans require 6 3/8 oz of slime. He stole another 2 3/5 oz
rusak2 [61]

Answer: 1/40

Step-by-step explanation:

Since we are told that Sinister Stan stole 3 3/4 oz of slime from Messy Molly and stole another 2 3/5 oz of slime from Rude Ralph. The total oz of slime stole would be:

= 3 3/4 + 2 3/5

= 3 15/20 + 2 12/20

= 5 27/20

= 6 7/20

We are told that his evil plans require 6 3/8 oz of slime, the amount needed for Sinister Stan for his evil plan would be:

= 6 3/8 - 6 7/20

= 6 30/80 - 6 28/80

= 2/80

= 1/40
