Prove th set then at every open set can be written as the union of a collection of open intervals. that is, prove that if u is an open where j is some index set and i, is an open interval for all j e j.

the solution is 12x-6y

=

x=0.8898305 is the answer to that equation

i belive the biggest ratio would be 18: correct me if im wrong

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
