The equation for the motion of an object with constant acceleration is d=vt+1/2 at^2 where d is distance traveled in ft, v is starting velocity in ft/s, a is acceleration in ft/s^2 and t is time in seconds. A racecar begins with a velocity of 200 ft/s and accelerates at 100 ft/s^2. Write an expression for the distance the car travels after t seconds. What is the GCF of the expression?

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

what i would say the best answer is a. 40.5

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
