Which is a factor of each term of the polynomial?

(7f2−12f)7f2-12f

a. f
b. 7f
c. 2f
d. 7

Step-by-step explanation:

The given expression is

As you can observe in the given expression, a common factor to all terms is , because it's present in each term.

To a factor be common, it has to be present in all terms, like in this case.

has as a factor.

has as a factor.

Therefore, the right answer is A.

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.
