Solve x^2 + 5x + 6 = 0

X=-2, X=-3

Step-by-step explanation:

The original formula would be x^2+bx+c. I factored out the problem and made a t chart that multiplies to 6 (a*c) and adds to 5 (b). 3 and 2 are the only ones that add to 5 and multiply to 6. I then grouped x^2+3x+2x+c because the c doesn’t change And 3x+2x are the multiples. Then i took out common terms and got (x+2)(x+3)=0 because we solve for x. Then when you move them you get -2 and -3 equal x. Hope it helps you.

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.
