Check if I rounded this number off correctly? Thank you :) x^2 = y^2 + 7^2 x^2 = y^2 + 49 x^2 = 7^2 + 49 x^2 = 49 + 49 x^2 = 98 x^2 = √98 x^2 = 7√2 7√2 = 3.2

    x^2 = 7√2 is the correct form. However, I think the decimal number can round off.

    If x = 3.1463, I would move to the thousandths place. 6 is larger than 5. x = 3.15 Then, I move to the hundredths place. x = 3.2
