Answer:
If no matter what choice of x my adversary makes, I can choose a y that makes the statement true, then the statement is true. Otherwise, it's false.
Step-by-step explanation:
According to the given situation, as we can see that the we cant find the y for the x i.e given that shows Parent (x) represented as Parent Of (x,y)
In mathematically,
Parent (x) = Parent (x,y)
This does not seems true
Therefore this statement is false
Hence, the fourth option is true
All other statements that are mentioned is false

Answer: Yes it is possible to construct a triangle and it will be an isosceles triangle.
Step-by-step explanation:
- The triangle inequality tells that for any triangle, the sum of the lengths of any two sides must be greater than or equal to the length of the remaining side.
Given sides of the triangle are 4 inches, 4 inches, and 7 inches.
Here, 
So by triangle inequality, a triangle with sides 4 inches, 4 inches, and 7 inches. is possible.
As it has two equal sides as 4 inches , then it must be an isosceles triangle.
Answer:
so we get as,
let, y = 2 - 9i
so the absolute value is |y|
so we get as,
|y| =
2-9i
so the absolute value is |y|
|y|=√
2 to the 2nd power plus 9 to the second power
so we get as,
|y|=
√81+4=√85
so the value is √85
