6. C
7. None
8. A and D
9. F and G
Step-by-step explanation:
See attachment for complete question
5. B, C and E
B, C and E are not parallelogram because they do not have 2 pairs of parallel sides
B and E are trapeziums while C is just a quadrilateral.
6. C
In (5) above, we established that B and E are trapeziums while C is not. This implies that only C is a quadrilateral.
7. None
A square is a parallelogram. So, it is not possible for a shape to be a square and not be a parallelogram.
8. A and D
A is a rhombus. D is a square and will be treated as a rhombus because all sides are equal.
9. F and G
These shapes have 2 pairs of parallel lines but all 4 sides are not equal; only the opposite sides are equal.

Alright, lets get started.
Numbers of visitors on Monday = 400
Numbers of visitors on Tuesday = 780
So, percentage change =
So, percentage change =
So, percentage change = 95 % : Answer
If same estimated percentage increase on next day also, means on Wednesday, the number of visitor will be = %
So,number of visitors on Wednesday =
Number of visitors on Wednesday = 1521 : Answer
Answer: D. (x+5)/(x-3)
Step-by-step explanation:
Domain = Set of all input values of a function.
range = set of all output values of a function.
Given: Domain: ; range =
We do not include a value for domain if it makes the expression indeterminant .
Since all the functions in options are fractions, here the denominator does not equal to 0.
But in option C and D, the denominator can be zero if x=3.
So , domain for then it
Also, for option C if
.which is not true.
Wher as in option D,
Hence, Domain: ; range =
is for option D.
