Question

what is the solution to the equation sqrt 2x+8 -6=4

Answer 1

\[\sqrt{2x+8} -6=4\]

Answer 2

1. add 6 to both sides
2. square both sides
3. subtract 8 to both sides
4. divide by 2

the end.

Answer 3

would it be x=\[\sqrt{5}\]

Answer 4

@abb0t

Answer 5

\[\sqrt{5}\]

Answer 6

Now. How did you get 5?!

Answer 7

I have no clue

Answer 8

im confused

Answer 9

Are you following the instructions I posted up above?

Answer 10

yes

Answer 11

To square both sides means \((\sqrt{2x+8})\)\(\sf \color{red}{^2}\) = (10)\(\sf \color{red}{^2}\)

Answer 12

my computer is not showing the formulas

Answer 13

When you square both sides, the square root goes away.

Answer 14

There should not even be a square root in your answer.

Answer 15

would it be x=1

Answer 16

No. How did you get 1?

Answer 17

I squared both sides then subtracted by 8 and got 2x=2 then divided

Answer 18

Go step by step.

First, start by adding six to both sides: \(\sqrt{2x+8}\) + \(\sf \color{red}{6}\) - \(6\) = \(4 +6\)
that gives you: \(\sf \color{blue}{\sqrt{2x+8}=10}\)

NOW, square both sides.

Answer 19

You square both sides so that you can solve for \(\sf \color{red}{x}\). You have it under the √ and in order to solve for it you MUST get rid of the √

Answer 20

the formulas are not showing up on my computer so I cannot see what you typed

Answer 21

would it be x=21?

Answer 22

No.

Answer 23

alright I give up I cant figure it out

Answer 24

You're not following my directions. Square both sides.

Remember, when you square something: \((10)\)\(\sf \color{red}{^2}\) = 100

Answer 25

Also, \((\sqrt{a})^2 = a\)

Answer 26

can you send it in that file again I cant see those things

Answer 27

so x=46

Answer 28

Yes! Correct.

Answer 29

finally alright thank you

Answer 30

Please practice.
