2 25 divided by 11 10 in fraction
koban [17]

Answer:

\frac{4}{55}

Step-by-step explanation:

\frac{2}{25}  \div  \frac{11}{10}

\frac{2}{25}  \times  \frac{10}{11}

\frac{2}{5}  \times  \frac{2}{11}  =  \frac{2 \times 2}{5 \times 11}

\frac{4}{5 \times 11}

=  \frac{4}{55}

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 :)
