The area is (BK) times (AK or CK).
If you have no numbers given, it's not possible to find the length of BK, or the actual number that represents the area.
Answer:
0.51km × 1000 = 510m
510m × (3×7) = 510m × 21 = 10710m in whole
Step-by-step explanation:
first we transform km to m (multiply by 1000)
then we count how much days are in three weeks ( 3 weeks × 7 days)
then we just multiply the meters per day × the days
99% it's true
the sequence is 4n-13, so substitute 107 into n and it will become 4(107)-13 =415
Answer: 918km^2
Step-by-step explanation:

Let x be the new dimension of the area;


Answer:
Step-by-step explanation:
Write the equation as:
Price of books times number of books + price of binders times number of binders = total price
So then the final answer is 3(2)+5(x)=16
