Answer 1

x^2 +3x^2=10^2

Answer 2

not sure how to do this

Answer 3

x^2+9x^2=100?

Answer 4

Can't you simplify the left side?

Answer 5

Im not sure im horrible at math

Answer 6

Adding similar variables?

Answer 7

oh so 4x^2

Answer 8

No, you had x^2 + 9x^2 = 100

Answer 9

We can add the x^2 terms, because they are similar.
10x^2 = 100; Next step?

Answer 10

divide by 10 which is 10 then square root 2

Answer 11

i mean square root x and 10

Answer 12

thank you

Answer 13

So what's your final answer?

Answer 14

rad 10

Answer 15

equals?

Answer 16

my teacher wants it in simplist rad form

Answer 17

...I know but we're solving for x.
x = sqrt(10). That's what I mean.

Answer 18

i said radical 10

Answer 19

The factors of 10 are prime, with no perfect squares too, so sqrt(10) can't be factored anymore.

Answer 20

I know, but you have to set it equal to 10. It's not just sqrt(10).

Answer 21

I know.

Answer 22

Set it equal to x*
