220x+5

Step-by-step explanation:

Do I simplify? if yes, here's an explanation

4x^4 that means, 4x*4x*4x*4x, do 4*4*4*4=256,so the first part is 256x.

6x^2 that means, 6*6=36, 36x

Then do , 256x-36x+5=220x+5

That's your answer!

Hope this helps!

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
