Answer:
-2x - (-1y) - (-3)
Step-by-step explanation:
Bacteria length = 1mm
It will triple four times by 40 min.
This can be shown as 3 to the power of 4; 3⁴ = 81
Original length * growth factor = final length
1 mm * 81 = final length
81 = final length
After 40 mins, the bacteria colony will be 81 mm in length.
