Answer 1

@Whitemonsterbunny17

Answer 2

yes

Answer 3

\[s=\sqrt{86}\]
\[A=s^{2}\]

so the area would be \[(\sqrt{86})^{2}\]

Answer 4

which is *not* B...

Answer 5

no...\[(\sqrt{a})^{2}=a\]

Answer 6

i actually ment 2 say times 4 but ok

Answer 7

so its c?

Answer 8

a simple yes or no sil do... i really have to finish this assighnment

Answer 9

will not sil

Answer 10

Answer 17

huhhhhhhhggggg

Answer 18

Okay, okay. I don't know how to do this kind of math, so I can't help you, but....
@mtbender74 and @surjithayer please be a little bit more descriptive, and go thoroughly through the steps with her.
And also, kindness is a key. Be kind, and be helpful.

lol

no1 named @serjithayer was in here

Answer 21

i'm always willing to take people through the steps, but if they don't understand what i said, i need to know where they are lost. if they want to know *how* to do the problem, i'll spend as long as it takes to get them to understand, but if they are simply looking for me to give them the answer, i won't...

that being said, do you still want my help @sissyedgar

Answer 22

yes i do

Answer 23

ok...so first things first...do you understand what square roots are?

Answer 24

yes

Answer 25

so \[\sqrt{9}=3\]
since (3)(3)=9

Answer 26

so if we looked at \[(\sqrt{9})^{2}\]that would be
\[(\sqrt{9})^{2}=(3)^{2}=9\]

still with me?

Answer 27

how do u type square root in the chat. kinda off subject i know but it is really cool

Answer 28

yes i am

Answer 29

you can use the equation button...or once you know how they are built, you can type them in directly :)

Answer 30

so what we have is that the square of the square root of any number is just the number...in other words
\[(\sqrt{a})^{2} = a\] regardless of the value of a

Answer 31

ok i really need to go because my mother is saying i need to hurry up and finish so we can go!!!

Answer 32

well...provided a is not negative...but don't worry about that

Answer 33

what the problem said is that the side of the square is \[s=\sqrt{86}\]

Answer 34

the formula for the area of a square is \[A=s^{2}\]

Answer 35

srry i will come bk n get the answer but i have to go now

Answer 36

so, the area of the square is
\[A=(\sqrt{86})^{2}\]

Answer 37

now, using the fact that \[(\sqrt{a})^{2}=a\], what do we have?
