If you are trying to write this as an equation I believe it goes like this:
3x-6=9
We don’t know the number that is multiplied by 3 so we just use x.

15-6=9
The radius of Earth is 6.3781 Kilometers
Answer:
Step-by-step explanation:
We know that
Length(l) = 1.5n + 9 ft
Width(w) = 5n - 1.5 ft
The formula for the perimeter(P) of a rectangle is:
So by substituting l and w we get :
