First find the area of each wall. This is length*width which would be 12*8.5=102. There are four walls in the room because it’s a square so that would be 102*4=408. So the total area you need to paint is 408ft one gallon will cover 75ft so 408/75=5.44 gallons of paint.
Alright, let's interpret it, first.
The question is asking us to first find two percent of 23,000, then right an equation.
Alright, first, let's find two percent of 23,000. To find that we must do 0.02*23,000
I got 460
So we know that Mastertown's population is increasing by 460 people per year. All we have to do now is plug that into the equation.
Population (y)= 460* amount of years (x)
So our final equation is y = 460x
Hope this helped! Ask any questions about it!
Answer: 
This is the same as saying 18*sqrt(2) or you could say 18√2
============================================================
Explanation:
We'll be using this square root rule: 
So we could have this as our steps:

Therefore, 
The basic idea is to first combine the roots using that rule. From there, we factor the radicand such that we pull out the largest perfect square factor. This will allow us to break the root apart and fully simplify it.
Answer:
12 which is on C
Step-by-step explanation:
use pathogoras theorem
a^2+b^2=c^2
16^2+b^2=20^2
256+b^2=400
b^2=400-256
b^2=144
b= square root of 144
b= 12
Hey mate here is your answer.
➛ 6(x-2) = 4(x+3)
➛ 6x-12 = 4x + 12
➛ 6x - 4x = 12 + 12
➛ 2x = 24
➛ x = 
⛬ x = 12
