2) Determine a raiz de cada equação a seguir (resolva descobrindo o valor do termo x desconhecido), considerando U = Q:
a) x - 17 = -9
g) 3. (x+2) + 5 = x + 12
b) 2x = -7
h) x + 4.(x - 1) = 9 -2.(x + 3)
c) 3x + 2 = 2x - 11
i) 5.(3x - 2) = 2.(6x + 3)
d) 2x = 16
i) 2.(3x-1) +2.(3-X)= 0
e) x = -5
2
k) 7.(x-1) = 2.(3x+1)
f) 2x + 14 = 5x - 1
1) 2.(3 - y) +7.(2 - y) = 15 - 4y​

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.

the height of the surface increases from the center out to the sides of the road

it is c!
