What is the perimeter of the triangle with sides ( 8x + 2) , (5x - 4) and (9x + 3)? Show all supporting work and your final answer. Explain the steps you used to find your answer.

The perimeter should be 22x + 1

Step-by-step explanation:

-In order to find the perimeter, you have to combine like terms:

-You first add up the integers that have the variable :

-Then, you add up the integers that don't have the variable :

-Result:

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.  

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.
