Question

The rate (in meters per second) that an object travels is the quotient of the distance (in meters) it travels and the time (in seconds) it takes to travel that distance. A particle traveled the distance of 3x^2-12 meters for ( x + 2 )seconds. Write the rate of the particle as a rational algebraic expression in simplest form.

Answer 1

Step-by-step explanation:

Rate

= Distance / Time

= (3x² - 12)m / (x + 2)s

= 3(x + 2)(x - 2)m / (x + 2)s

= 3(x - 2) m/s.
