If the sides of a triangle are in the ratio 3:4 : 5 and its perimeter is 24 cm, find
the measure of each side of the triangle.​

let be side of triangle be 3x,4x,5x

3x+4x+5x=24

12x=24

x=24/12

x=2

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

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
