Answer 6

No, try again.

Answer 7

my computer is a bit older so its losing signal and crashing so i have to keep refreshing an it takes a while sometimes

Answer 8

49 sorry i did 173/3

Answer 9

m^2 = 49

That means what number times itself = 49.

What is one number that behaves that way?

You may have a square root key on your calculator. I don't know but this square root is pretty easy to get out of your head.

Answer 10

I am not typing. This crazy message says that but I am not.

Answer 11

Go to Google and in the search box, enter this: "square root of 49" and tell me what it says.

Answer 12

@desfields901

Answer 13

it works

Answer 14

7

Answer 15

Listen up.

Every number has two square roots.

7 is one of the square roots of m.

-7 is the other. So, remember the calculator will give you the positive root but you have to get the negative root out of your head.

Answer 16

I mean to say square roots of 49, not m.

Answer 17

okay

Answer 18

3 times (7)^2 = 147
AND
3 times (-7)^2 = 147

Answer 19

Next Practice Question

Answer 20

okay so how did we get 7 again

Answer 21

Divide 147 by 3 to get x^2 = 49. Then take square roots to get 7 and -7.

We divided by 3 to begin with because 3x^2 = 147 and you have to divide by 3 to isolate the x^2 term and then solve for x.

Answer 22

you got the 7 by using Google, entering square root of 49

Answer 23

7,-7
