D. 9, -9

Answer 1

im back lol

Answer 2

YEA! XD TOO MUCH SWAG IN HERE NOW XD!!!!

Answer 3

Square both sides:D

Answer 4

lol

Answer 5

I dont get what I have to do with the solution on B and C

Answer 6

I know A and D wont work but how would I find out the rest?

Answer 7

B. \[\pm 4\sqrt{6}\]

Answer 8

@ChihuahuaAdorer Do you mind explaining?

Answer 9

yes please, I dont want the anwser (I mean I do) But I want to know how so I dont have to keep asking what the anwser is...

Answer 10

well you have to square root each side so \[x = \sqrt{96}\]
and since that is not one of the choices you have to simplify the square root.
to do this, find out what highest perfect square multiplies by another number to get 96.
In this case it would be \[\sqrt{16 * 6} = \sqrt{96}\]
since 16 is a perfect square you can simplify the square root so it ends up \[\pm 4\sqrt{6} \] I hope that makes sense! :)

Answer 11

yea it actually, thanks :) mind helping me with 1 more?

Answer 12

sure!

Answer 13

Its a simple question but I dont know how to solve it and when I do try to solve it, I end up with 248+ results when I need 28 >.<
Solve the equation.

8x^2 – 4 = 28

A.
2, –2

B.
4, –4

C.
8, –8

D.
16, –16
I think its C But then again Im soo confused

Answer 14

First you want to add 4 to each side: 8x^2 = 32
Then divide by 8 on each side: x^2 = 4
Square root each side: \[x = \pm 2\]

Answer 15

so A would be your answer!

Answer 16

oh... I did that sooo wrong XD Thank you soo much! :)
