410 -289 = 121 . . . . feet
__
If you like, you can think of the sub's elevation relative to the surface as changing from -410 feet to -289 feet. The difference is then an increase in elevation (rise) of ...
-289 -(-410) = -289 +410 = 121 . . . feet

Answer:
Ribbon can't be enough
Step-by-step explanation:
Markin is making a flag shaped like a square. Each side measures 13 m. He wants to add ribbon along the edges. He has 48 m of ribbon. Does he have enough ribbon? If it is not enough,how much more ribbon needed?
Given :
Side length of square shaped flag = 13 m
Length of ribbon markin has to add along edges = 48 m
To know if the ribbon will enough ; we obtain the perimeter of the square shaped flag ;
4 * side length
4 * 13 = 52 meters
52 > 48
Since the perimeter is greater than the length of ribbon, then ribbon can't be enough
(2x+2)(10x^2 - 6x + 8) =
2x(10x^2 - 6x + 8) + 2(10x^2 - 6x + 8) =
20x^3 - 12x^2 + 16x + 20x^2 - 12x + 16 =
20x^3 + 8x^2 + 4x + 16 <==
