<h3><u>Given</u><u>:</u></h3>
AE = 13
BE = 6
CE = 8
BC = 10
AB = AD
BC = DC
<h3><u>To</u><u> </u><u>Find</u><u>:</u></h3>
The length of BD.
<h3><u>Explan</u><u>ation</u><u>:</u></h3>
DE = BE ( Diagonals of a kite are the perpendicular bisector of each other )
DE = BE = 6
BD = BE + DE = 6 + 6 = 12
<h2><u>Answer</u><u>:</u></h2>
The length of BD is <u>12</u>.
The correct option is <u>Option B. 12</u>
Answer:
Because the living things need to survive somehow.
Explanation:
Malthus theory of population mention that this will increase in a geometric way, meanwhile the food to feed population will increase in an arithmetic way, so in one point, people will fight for food to survive.
Later, Darwin took this concept of struggling for surviving, how a couple of living things normally have double or triple of offspring, that means that by passing the time, there are more living things that the food that they can reach. He thought also, how a living thing can survive to the different conditions of the environment like heat, food, preys, etc. Later Wallace had the same conclusion about the natural selection but using different methods.

<u>Answer:</u>
The law of demand states that "price decreases lead to greater demand and limited supply, which occur during excess demand" explains the relation between the law of "demand and excess demand".
<u>Explanation:</u>
- The "law of demand" states that when the "price of a commodity decreases", there is a relative surge in the demand for the commodity.
- Owing to greater demand, the supply falls short and is thus termed as 'limited'.
- This happens because when the price decreases, the affordability of the commodity increases and the number of customers willing to buy the commodity automatically increases.
