Answer:
We know that the square has 5 centimeters sides.
The area of a square is defined as

Where
. Replacing this value, we have

Therefore, the area of the square is 25 square centimeters.
Its perimeter is defined as the sum of all sides, so

Therefore, its perimeter is 20 centimeters.
Answer:
The restaurant would sell more than a hundred omelets. 104.4 omelets
Step-by-step explanation:
The restaurant serves breakfast from 6:09 am until 10:30am. This means 4 hours 21 minutes. One hour is 60 minutes. Four hours will be 240 minutes. Then, 4 hours 21 minutes will be 261 minutes.
If 6 omelets are sold each 15', how many omelets will be sold in 261 minutes. This rule of three render that 104.4 omelets will be sold in 261 minutes
A=LW and L=W+9 so
A=(W+9)W
A=W^2+9W
W^2+9W-A=0, since A=220
w^2+9w-220=0
w^2+20w-11w-220=0
w(w+20)-11(w+20)=0
(w-11)(w+20)=0
Since w>0
W=11 ft, and since L=W+9
L=20 ft
Answer:

Domain: 
Step-by-step explanation:
Given

Required
Determine f(x) and its domain
To determine f(x), we replace 5x with x in f(5x)
So, we have:


Take LCM



To get the domain, we set the denominator as
