Find the limit of the function by using direct substitution. (2 points) limit as x approaches three of quantity x squared plus eight x minus two.

Step-by-step explanation:

The function is: , and we need to find the limit when x approaches 3 of it by what is called direct substitution. This method can be used as long as the function is not undefined at the point in question.

In this case, as the function is a polynomial, it is well defined for all real numbers, and the limit can be evaluated just by substituting the value x with the number "3" one wants to approach:

it is c, trust i got your back lol

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.
