Which expression is equal to (x+-4x+2)

Using synthetic division, with divisor -4 stemming from factor (x+4), we find the coefficients of the quotient:

-4   /     -3          -4             2

                         12             -2

             -3           8              0

The quotient is then -3x + 8, using the coefficients derived using synth. div.

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.
