Answer:
The given quadrilateral is a parallelogram.
Step-by-step explanation:
If a quadrilateral is a parallelogram , then the opposite sides would be equal.
Here we are going to equate the length of 1 pair of opposite sides to find the value of x and use this value of x to verify whether the other pair of opposite sides are equal.
AB = 6x
BC = 3x
DC = x + 15
AD = 9
Equate AB and CD,
6x = x + 15
5x = 15
x = 3
Now BC and DA should be equal.
BC = 3x = 9
Also DA = 9
As we can see, the other pair of opposite sides are also equal.
Quadrilateral ABCD is a parallelogram if both pairs of opposite sides are congruent.
Hence , the given quadrilateral is a parallelogram.

Step-by-step explanation:
Answer with Step-by-step explanation:
We are given that
P(A)=0.4 and P(B)=0.7
We know that

We know that
Maximum value of
=1 and minimum value of
=0






It is not possible that
is equal to 1.1


Multiply by (-1) on both sides

Again, 



Multiply by (-1) on both sides

Hence,
