How do you factor: 5x^3+30x^2+45x (please show steps)

5x³ + 30x² + 45x = 5x (x+3)²

Step-by-step explanation:

Given: 5x³ + 30x² + 45x

Take 5x as a common

5x³ + 30x² + 45x

= 5x ( x² + 6x + 9) ⇒ Factor ( x² + 6x + 9)

= 5x (x+3) (x+3)

= 5x (x+3)²

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
