Answer:

LCM = x(x - 2)(x - 6)(x + 2).

Step-by-step explanation:

x^2 - 4x - 12 = (x - 6)(x + 2)

x^2 - 8x + 12 = (x - 2)(x - 6)

x^3 - 4x = x(x - 2)(x + 2)

Taking into account the common factors:

LCM = x(x - 2)(x - 6)(x + 2)

Josiah skateboards from his house to school 3 miles away. It takes him 36 minutes.
nikdorinn [45]

Using the speed - distance relationship, the number of minutes it will take Josiah to cover a distance of 2.5 miles is 30 minutes.

<u>Calculating Josiah's speed</u> :

  • <em>Speed = (distance ÷ time) </em>

Speed = (3 ÷ 36) = 0.08333 miles per minute.

<u>Time taken to cover a distance of 2.5 miles</u> :

  • <em>Time taken = (Distance ÷ Speed) </em>

Time taken = (2.5 ÷ 0.08333) = 30 minutes

Therefore, it will take 30 minutes for Josiah to cover a distance of 2.5 Miles
