(2m+3)(4m+3)=075 points! tell me how to do this! plz? !

Hi!

We can remove the parentheses.

2m+3+4m+3=0

Simplify by combining like terms.

2m+4m+3+3=0

6m+6=0

Subtract 6 from both sides.

6m+6-6=0-6

6m=-6

Divide by 6 on both sides.

6m/6=-6/6

m=-1

The answer is m = -1

Hope this helps! :)

2m+3=0

4m+3=0

Set the first factor equal to 0 and solve

m= -3/2

Set the next factor to 0 and solve

m= -3/4

The values that make (2m+3)(4m+3)=0 are true.

m= -3/2,-3/4

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.
