Which of the following terms best describes the three side lengths of the
triangle below?

B. Pythagorean triple

Step-by-step explanation:

To prove Pythagorean triple, we must prove that

ML² + LN² = MN²

or MN = √( ML² + LN²)

= √( 9² + 12²)

= √( 81 + 144)

= √( 225)

= 15 = value of MN given in diagram (proven)

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.

4+4+2x

or

2x+8
