4. Which statement is true about the values of two expressions below? Expression A: 3x(8+4)

Expression B. 8+4

A. The value of expression B is 3 times the value of expression A.

B. The value of expression A is 3 times the value of expression B.

C. The value of expression A 3 times more the value of expression B.

D. The value of expression B is 3 times more than the value of expression A.
​

Both B and C should be correct

Step-by-step explanation:

I'm assuming the x in Expression A is a multiplication symbol. If it is not, please tell me and I will change my answer.

Expression B has the value of 8+4 or 12.

Expression A is 3 times (8+4). You could also say that Expression A is 3 times Expression B.

Since both answer B and C say this, they should both be correct.

step-by-step explanation:

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.
