An equivalent expression would be s+15
You simplify the expression.
So yea the answer is s+15
Answer:
80 ft
Step-by-step explanation:
if 1 = 20 then 20 is width but ? is length
1=20
2=40
3=60
4=80

Answer:
27 by 27
Step-by-step explanation:
Let the sides be x and y. The problem is essentially asking:
Given 2(x+y)=108, maximize xy.
We know that x+y=54. By the Arithmetic Mean - Geometric Mean inequality, we can see that 
. Substituting in x+y=54, we get 
, meaning that 
. Equality will only be obtained when x=y (in this case it will generate the maximum for xy), so setting x = y, we can see that x = y = 27. Hence, 27 is the answer you are looking for.
I guess it could represent a situation where you have
of a cake left and you have to share it with three of your friends (in addition to yourself). So that's four people sharing
of a cake.
