Step-by-step explanation:

x + 7) x³ + 7x²- 2x + 6 ( x²- 2

        x³ + 7x²

                     -2x + 6

                     -2x - 14

                           +20

Therefore, we can write the expression in the remainder quotient form as,

no one knows lol

step-by-step explanation:

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.
