Question

Find the value of x. express your answer in simplist radical form

if u answer 1st and correct I'll give u brainilest​

Answer 1

`3√(2)`

Explanation:

`x^(2) = 3^(2) +3^(2) \\x^(2) = 9+9\\x^(2) = 18\\x= √(18) \\x= √(9*2) \\x=3√(2)`

Answer 2

3
`√(2)`

Explanation:

Use the pythagorean method: a^2 + b^2 = x^2. Your a and b are both 3, and your c is x, so...

3^2 + 3^2 = x^2

9 + 9 = x^2

18 = x^2

`√(18)` = x

(18 = 2 * 3 * 3, 3 has a pair, take that out)

3
`√(2)` = x
