We have a triangle with sides of (8x + 2) , ( 5x - 4) , and ( 9x + 3). Explain how you find the perimeter of a triangle.

Step-by-step explanation:

This is incomplete question as the perimeter of the triangle is not give

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
