Recently, while working on some math homework, Carmen and Mario got into a little argument. During the dispute, a part of their assignment was destroyed. All that remained of one
particular problem is shown below.

Carmen was furious. “Way to go, Mario! Now there is no way to get this problem correct! We don't
even know what f(x) is.”
“Wait a minute!” Mario quickly responded. “I’m pretty sure we can solve this anyway.”
Carmen shook her head.
Who is correct? Explain completely why and what the other person might be forgetting.

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

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.
