Is it possible to square root a negative number?

2 answers:

<span>No because a negative times a negative will be positive and it will not equal a negative number. the square root cannot be one negative and one positive because that is against the definition of a square root.

No because you had no number which were negative after you squared. if you do every number goes back positive after you squared it i think.

Answer:

72 beats per minute

Step-by-step explanation:

So if a female has a pulse rate of 80 beats per minute but her pulse rate is lowe by 10%

First, we need to find what 10% of 80 is

.10 Times 80 = 8

Now we subtract 8 from 80

80-8=72

The female has a heartbeat of 72 beats per minute (bpm)

Katie solved the equation by completing the square.

emmainna [20.7K]

Katie has equation $x^2+12x-7=0$ and wants to solve it completing the perfect square. In order to do it, first rewrite 7 in right side:

$x^2+12x=7.$

Then note that $12x=2\cdot 6\cdot x,$ so Katie has to add $6^2=36$ to both sides (because $x^2+12x+36=x^2+2\cdot 6\cdot x+6^2=(x+6)^2$ ):

$x^2+12x+36=7+36,\\ \\(x+6)^2=43.$

Answer: correct choice is C.
