Sound travels 10200m farther through stone in 17 seconds than through aluminium

Speed of sound in aluminium =  3100 m/s

The speed of sound in stone = 3700 m/s

Time taken = 17 minutes

Distance traveled = Speed  x  Time

Distance traveled by sound in aluminium in 17 seconds  = 3100    x  17

Distance traveled by sound in aluminium in 17 seconds  = 52700 m

Distance traveled by sound in stone in 17 seconds =  3700   x  17

Distance traveled by sound in stone in 17 seconds =  62900 m

Difference in the distance traveled = 62900 - 52700

Difference in the distance traveled = 10200 m

Sound travels 10200m farther through stone in 17 seconds than through aluminium

PLEASE HELP!!! <br> Solve the quadratic equation by completing the square.
kow [346]

The values of x in the quadratic equation using completing the square method are x=-4 \pm \sqrt{5}.

Given information:

The quadratic equation is x^2+8x+11=0.

It is required to factorize the given quadratic equation using completing the square method.

<h3>How to factorize a quadratic equation?</h3>

Use completing the square method to solve the equation as,

x^2+8x+11=0\\(x)^2+2(x)(4)+4^2-4^2+11=0\\( (x)^2+2(x)(4)+4^2)-4^2+11=0\\(x+4)^2-16+11=0\\(x+4)^2=5\\(x+4)=\pm \sqrt{5} \\x=-4 \pm \sqrt{5}

Therefore, the values of x in the quadratic equation using completing the square method are x=-4 \pm \sqrt{5}.
