Can someone please explain this to me I’m so confused and I have a quiz on this tomorrow

                               x^2 = 16/100
We must solve for x by taking the square root of both sides.
But imagine x^2 = 9. x = 3 is a solution because 3^2 = 9. But x = -3 is also a solution because (-3)^2 = 9. So we need to add the plus and minus sign to account for all of our solutions.
                     √x^2 = √(16/100)
We square root both sides to remove the exponent 2 on x. Then
                         x = ±√(16/100)
Then we have to use a Property of Radicals which is √(x/y) = √(x) / √(y).
Then the square root of 16 is 4 and the square root of 100 is 10. 4/10 is 2/5 simplified.

Suppose y varies directly as X, and Y equals 16 when x equals 8 find y when x equal 16
Korolek [52]
When
y = x \\ y = 16 \\ x = 8
you would have to use comon multiples to find what both numbers have in common, a short way of finding this would be
16 \div 8 = a
where (a) is the answer of the equation, (a) would be 2 because 8*2=16 meaning
y = 2x
