802 is not apart of the decimal. (I might sound stupid but I dont remember expanded form as much.) Only the 6 is apart of the decimal itself. 802 is just numbers. The 6 is pretty much the decimal.
The vector sum of two vectors as (7,5) and (13,-5) is given by
which can be written in point form as (20,0) .
<u>Step-by-step explanation:</u>
Here we have , two vectors as (7,5) and (13,-5) Which are represented as :

Addition of vector is as same as normal addition of integers as :
⇒ 
⇒ 
⇒
,
where i & j are the unit vectors in direction x-axis and y-axis respectively.
The vector sum of two vectors as (7,5) and (13,-5) is given by
which can be written in point form as (20,0) .
Answer:
194.4
Step-by-step explanation:
Formula for finding the area of any polygon :
number of sides (n) x 0.5 x length of sides (s) x apothem (a)
Area = 9 x 0.5 x 7.2 x 6 = 194.4
hope this helps :)
N=9

n=9.333333333333333

that is 15 3's by the way.
