Answer: width would be 7 feet and the length would be 26
Step-by-step explanation:
width : w
length: 19 +w
2l + 2w = 66
2(19+w) + 2w= 66 distribute
38 + 2w + 2w = 66 add the w values
38 + 4w =66 subtract 38 from both sides
4w = 28 divide by 4
w= 7
19+7= 26
l=26

Answer: Michael has 87 comic books while David has 41 comic books.
Step-by-step explanation:
Let x represent the number comic books that Michael has.
Let y represent the number of comic books that David has.
Michael has 5 more comic books than double David's collection. The expression would be
x = 2y + 5
If together they have a total of 128 comics, it means that
x + y = 128- - - - - - - - - -1
Substituting x = 2y + 5 into equation 1, it becomes
2y + 5 + y = 128
3y + 5 = 128
3y = 128 - 5
3y = 123
y = 123/3
y = 41
Substituting y = 41 into x = 2y + 5, it becomes
x = 2 × 41 + 5
x = 87
