If f(x)=5x-2and g(x)=2×+1,find (f+g)(x) a. 7x-1 b. 7x-3 c. 3x-1 d. 4x-3

a. 7x-1

Step-by-step explanation:

The given functions are;

and .

We want to find;

This implies that:

Regroup similar terms;

Combine similar terms;

The correct choice is

a. 7x-1

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.

answer: 12,000
