Answer:
4308 fish
Step-by-step explanation:
Well you can just look at the answer and tell
14327 is not possible at all, thats an increase
839 is way too low
7680 doesn't make sense at all
4,309 is the most reasonable
Let the original side length be x. Then (x+2)^(in)^2 = 121 sq in.
Thus, x^2 + 4x + 4 = 121;
x^2 + 4x - 117 = 0 = (x-13)(x+9) = 0. Then x = 13 and x = -9.
We need to discard the negative result (-9).
The side of the original square is 9 inches. (answer)
Check: does (9+2)^2 = 121? Does 11^2 = 121? YES.
