Answer:
B. 22 cm
Step-by-step explanation:
Perimeter of a parallelogram is 2(l+w)
= 2(8+3)
=2(11)
=22cm
Answer:
Option (D).
Step-by-step explanation:
Initial population of the deer 
= 4800
Decrease in the population of the deer after every 8 years = 
Decrease in population is an exponential process, so the expression representing population will be,
Where 
is the population after 'x' slots of 8 years.
r = fraction of decrease in the population
x = 
By substituting the values of r and x in the expression,
Therefore, Sylvia should do few corrections in her expression.
(8) should be replaced by (
) and 
should be replaced by 
.
Option D. will be the answer.
<span>The diagonals of a parallelogram bisect each other.
So we just equate the two equations BE and DE
2x^2 - x = x^2 + 6
2x^2 - x - x^2 - 6 = 0
x^2 - x - 6 = 0
This is quadratic eqn. So we obtain.
(x - 3) ( x + 2) = 0
Setting each to 0 and solving for x, we have that x = 3 and x = -2
So we have two possible values for BD.
But Since BE = DE then we can simply double each
If x = 3 BD = 2 (2(3)^2 - 3) = 2 ( 18 - 3) = 30 units
If x = - 2 BD = 2((-2)^2 -3 ) = 2 (8 - 3) = 10 units</span>
