One hundred and thirty-nine thousand, eight hundred and fifty-two. ;) Hope that helped
If the moving object is undergoing constant acceleration, then

(take the average of the initial and final velocities, if they're given)
If you don't know the acceleration or initial/final velocities, then you have to resort to the usual definition,

where
is the change in position and
is the duration of the interval.
First, always draw. You learned to draw in kindergarben (Yes I spelled it like that on purpose LOL) for a reason.
1) Draw your rectangle on a piece of paper or paint.
2) Scale factor each side to enlarge which means you're going to multiply.
--- Note if it said 'to reduce' then you would divide.
3) Then find the area by multiplying the two given sides (12 x 6 = 72).
4) Don't forget your unit of measurement - 72ft²
So your answer is D.
Answer:
5.29 * 10^-5 is written as scientific notation.
For example:
9200 ---> 9.2 * 10³
123000 ---> 1.23 * 
8640000 ---> 8.64 * 
where first number/letter should be between 1 - 10.
