Which polynomial identity will prove that 16 = 25 − 9?
difference of squares
difference of cubes
sum of cubes
square of a binomial

 Difference of Squares

Step-by-step explanation:

Since, According to the polynomial identity of the Difference of Squares,

If a and b are two numbers or polynomials then we can write,

Here our expression,

16 = 25 − 9

Since, we can write,

⇒  ( By applying polynomial identity of  Difference of Squares )

⇒

⇒

Hence proved.

answer: idk

step-by-step explanation:

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
