Answer:
I'm assuming you don't want to paint the floor.
1220
Step-by-step explanation:
25 * 8 = 200. Now we multiply that by 2 to get 400. Those are the 2 walls.
The ceiling is 25 * 20 = 500.
20 * 8 = 160. Now we multiply that by 2 to get 320. Those are the 2 walls.
500 + 400 + 320 = 1220
4 times 1 equals 4 then do 81 minus 4 which equals 77 so 77 is your answer
If we plug 2 in for x we get
4^2 or 4 x 4
And
2^4 or 2 x 2 x 2 x 2
4 x 4 is 16 and 2 x 2 x 2 x 2 is also 16
So when x=2 the difference between the 2 expressions is 0
