P / 9 = 72
Multiply both sidess by 9
P / 9 (9) = 72 (9)
p = 648
First, 
, and if we multiply 
by 
we get
Subtracting this from the numerator gives a remainder of
Next, 
, and if we multiply by 
we have
and subtracting this from the previous remainder, we end up with a new remainder of
Next, 
, and if we multiply by 
we get
Subtracting from the previous remainder, we get a new remainder of
which contains no more factors of 
, so we're done.
So,
D<-7
{d | d<-7}
Hope this helps!
Answer:
the formula for finding the perimeter of a rectangle is P=2L+2W
an example of how to find the perimeter is
Explanation:
For a rectangle, its perimeter is the sum of all for sides.
The rectangle has a perimeter of 54. Find the lengths of the unknown side. That is, find S.
54=20+20+S+S
Simplify
54=40+2S
Solve for S
14=2S
S=7
Step-by-step explanation:
