The subset of A is B = {1, 2} and the proper subset of A is C = {1,2,3,4}
<h3>How to create the Subset and Proper Subset of the set?</h3>
The set is given as:
A = {1,2,3,4}
Subsets of a set are sets that can be found in another set
An instance of this is
B = {1, 2}
Because all the elements of set B are in set A
Proper subsets of a set are sets that contain the exact elements found in another set
An instance of this is
C = {1,2,3,4}
Because set C and set A have the same elements

Answer: it’s D
Step-by-step explanation:
So assuming L=legnth
xd=y(L-d)
divide both sides by y
(xd)/y=L-d
add d to both sides
((xd)/y)+d=L
