Answer:
Step-by-step explanation:
5/3=1/n(do cross multiplication)
3*1=5*n
3=5n
3/5=n
C would be the answer, which is 9x+9y
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)
