Me i am frusterated someone answer u ! i am crying trying cause no one seems to me someone me u! the question : find the expression that is not equivalent ,for the problems 9-16 below

First of all, don't cry. Second of all, try to post a clearer picture because it was a bit tough to see. Third of all, here are the answers:

In row 9, S is wrong because it is 27x+24y, it should be 36x+24y
In row 10, A is wrong because it is 4+20x, it should be 20x
In row 11, G is wrong because it is 15ab, it should be 10a+5b
In row 12, I is wrong because it is 15x+6y, it should be 15x+10y
In row 13, O is wrong because it is 22a+6, it should be 28a
In row 14, T is wrong because it is 14x, it should be 22x
In row 15, K is wrong because it is 15x+y, it should be 15x+3y
In row 16, T is wrong because it is 14n+84m, it should be 12m+14n

Also on another note, this might be intimidating but it is mostly adding/multiplication of variables. So if you don't know them, you might want to double check that you know how to handle variables in the future;)

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.

\text{Area of walls and ceiling}=(2*40*15)+(2*3*15)+(40*3)

\text{Area of walls and ceiling}=1200+90+120

\text{Area of walls and ceiling}=1410

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,  

\text{ The total painting cost}=10*(\frac{1410}{25})

\text{ The total painting cost}=10*56.4=564

Therefore, the total painting cost is $564.  

Tiles will be required for floor. Let us find the area of floor.

\text{Area of floor} = 40*3\text{ square meters}

\text{Area of floor} =120\text{ square meters}

Given: 1m squared floor tiles costs $3. So,

\text{Total cost for tiles} = 3*120 = 360

Therefore, the total cost for tiles is $360.  

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

\text{Combined total cost}= 564+360 = 924

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

please give this answer a brainliest!!
