Let x,y be two different numbers
suppose x^2=y^2
then x^2-y^2=0
which yields (x+y)(x-y)=0
so either x=y or x=-y
In any case, x and y must be the same value
also when a vairable is squared like y=x^2
we must note that there are 2 possible solutions
x=(+/-)sqrt(y)

Hi!
There are two ways to do this.
1. Start with the first part of the decimal, (4.) then divide 3/7 to get the second part.
3/7 = 0.43
4.43
2. Convert the mixed number 4 3/7 to a fraction.
4 x 7 = 28
28 + 3 = 31
31/7
Now convert that into a decimal.
31/7 = 4.43
The answer is 4.43
Hope this helps! :)
