Answer 3

im confused again

Answer 4

@ivettef365 can you help

Answer 5

you have

y = 3x

x^2 + y^2 = 40 -> substitute the y for 3x

Answer 6

you have

x^2 + (3x)^2 = 40
x^2 + 9x^2 = 40 (you can combine like terms so you add)
10x^2 = 40 (now divide by 10) and you have
x^2 = 4 (now square both sides)
\(\sqrt{x^2}\) = \(\sqrt{4}\) can you take it from here

Answer 7

what do i do

Answer 8

what is \(\sqrt{x^2}\)

Answer 9

\[\sqrt{4}\]

Answer 10

what I meant what is the \(\sqrt{x^2}\) = x
and \(\sqrt{4}\) = 2

so you have x = 2

Answer 11

ooooo ok
