The square below has an area of x^2- 10+ 25 square meters. What expression represents the length of one side of the square?​

9514 1404 393

 (x -5) meters

Step-by-step explanation:

We assume the area is supposed to be ...

  A = s^2 = x^2 -10x +25

This is a perfect square trinomial, so can be factored as ...

  A = s^2 = (x -5)^2

Then the side length can be represented by the expression ...

  s = (x -5) . . . . meters

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
