Answer:
The box is 7.5 in long.
Step-by-step explanation:
Calculate the total surface area of the sides of this box (neglecting the ends).
If the base is 3" by 3" and the length of the box is 6", then the total surface area (without ends) is 4 times 3" by x, or 12x in². 80% of this "lateral surface area" is 0.80(12x in²), or 9.60x in° and this 9.60x in² represents the surface area covered b y the label. That label surface area is 4(3 in by 6 in), or 72 in²
Equating 9.60x in² and 72 in² and solving for x yields x = (72 in²) / (9.60 in²:
x = 7.5 in
The box is 7.5 in long.
As both are adding same number of comic books each months, they will not have same number of books. Adrian will have 4 more comic books.
Step-by-step explanation:
Given,
Adrian starts with 12 comic books and add 4 each month.
Let,
m be the number of books.
A(m) = 4m+12
Rory starts with 8 comic books and add 4 comic books each month.
R(m) = 4m+8
As both are adding same number of comic books each months, they will not have same number of books. Adrian will have 4 more comic books.
