According to the information given above,
A = [2, 4]
B = [5, 6]
A Intersection B = [1, 7]
The element of {A N B]! are those elements which are in both set A and set B with the exception of the elements that forms the intersection between them.
Thus, for the question given above,
{A N B]! = [2, 4, 5,6].
Answer:
Assume that the expression is:
r = √(A)/3
Multiply both sides by 3:
3r = √(A)
Finally, square both sides to get:
A = (3r)²
= 9r²
I hope this helps!

Answer:
3/18 or 2/6
Step-by-step explanation:
5/18 -1/9 =(1×5)/(1×18) -(2×1)/(2×9) =5/18 -2/18 =(5-2)/18=3/18
Answer:
Combine points A with C and A with B. Consider ΔABD and ΔACD:
1. AD is common side, then AD\cong AD;
2. CD\cong BD - given in the diagram;
3. \angle ADB\cong \angle ADC .
By SAS Postulate, \triangle ABD\cong \triangle ACD . Congruent triangles have congruent corresponding sides and congruent corresponding angles, so AC\cong AB .
From this proof you can see that correct choice is option D (In triangles ABD and ACD, two sides and an included angle are equal.)
