Question

another one i'm not sure of

Answer 1

Do you know Pythagoras' theorem?

Answer 2

yes i do.

Answer 3

a^2 + b^2 = c^2

Answer 4

Why not use that here then?

Answer 5

i did, but my problem is I'm complicating it in my mind.
i'm not sure whether i choose 4 or 4 sq.root3 or 12.
i don't know.

Answer 6

i really don't think it's 12 though.
i think it's 4 but i don't know how i would come up with a way to prove it.
and it's probably wrong.

Answer 7

so...?

Answer 8

when exactly are you supposed to use a sq. root symbol with your answer?

Answer 9

See the answer is sqrt 144
You write square root when something is being square rooted XD
sqrt a^2 = a !!
Like that! :)
