What is the answer for -5x^2=-500 by factoring the quadratic equation?

evablogger [386]

Answer:

x=10

Step-by-step explanation:

I think..i tired

Divide both sides by 55.

{x}^{2}=-\frac{500}{5}x2=−5500

Simplify \frac{500}{5}5500 to 100100.

{x}^{2}=-100x2=−100

Take the square root of both sides.

x=\pm \sqrt{-100}x=±√−100

Simplify \sqrt{-100}√−100 to \sqrt{100}\imath√100ı.

x=\pm \sqrt{100}\imathx=±√100ı

Since 10\times 10=10010×10=100, the square root of 100100 is 1010.

ArbitrLikvidat [17]

Answer:

The height of the rock is 15 mm.

Step-by-step explanation:

Given : Cristian put a large rock on the bottom of the terrarium he made for his pet turtle.

To find : How high is the rock?

Solution :

The rock is a right rectangular prism 10 cm wide by 12 cm long.

Let the height be 'h'.

The volume of the right rectangular prism is $V=L\times B\times H$

i.e. $V=10\times 12\times h$

$V=120h$

The rock displaces 1800 cm³ of water.

i.e. The volume of the right rectangular prism is equal to the rock displaces of water.

So, $120h=1800$

$h=\frac{1800}{120}$

$h=15$

Therefore, the height of the rock is 15 mm.
