Answer 1

@Vocaloid @Hero

Answer 2

Let's go over the 1st one:
\(\sqrt{x + 3} + 6 = 9\)

First subtract 6 from both sides. Let me know what you get afterwards. Please post your steps here.

Answer 3

6+3=9

Answer 4

6+9=15

Answer 5

like that?

Answer 6

@Catherine, we're SUBTRACTING. And btw, you can use that equation button below the chat to write your equivalent equations.

Answer 7

omg. sorry

Answer 8

6-3=3
9-6=3

Answer 9

@Katherine, like this:
\(\sqrt{x + 3} + 6 - 6 = 9 - 6\)

Answer 10

it gave me 72

Answer 11

I don't know how you get 72 from that. All we're doing is 6 - 6 = ? and 9 - 6 = ?

Answer 12

yaaa that's what i did earlier

Answer 13

I'm showing you how to subtract 6 from both sides. Let me write it out for you:


When you were doing it you kept getting numbers like "15" but then you were doing some unnecessary calculations as well. At no point is there ever a computation such as "6 - 3 = 3"

Answer 14

Next we have to square both sides. Are you aware of how to do that?

Answer 15

square both sides.. hm ok

Answer 16

i'm sorry, i've been on this question for 4 hrs now. and I'm all confused lol

Answer 17

let me try it out

Answer 18

when u say square both sides, which numbers do I add?

Answer 19

"Squaring" does not imply addition. You might want to try reviewing the tutorials for the instruction related to this problem.

\(\left(\sqrt{x + 3}\right)^2 = 3^3\)

Answer 20

\(\left(\sqrt{x + 3}\right)^2 = 3^2\)

Answer 21

it gave me 6

Answer 22

so, D?
