To find the height of Plant B after any number of months, we can use the equation for height in terms of time. The height of the plant starts at 8 cm and grows at a rate of 1 cm per month.
Let \( t \) represent the time in months and \( h \) represent the height of the plant in centimeters. The equation can be formulated as:
\[ h = 8 + t \]
This equation indicates that the height \( h \) is the initial height (8 cm) plus the growth, which is equal to the time \( t \) (in months) multiplied by the growth rate (1 cm/month). Since the growth rate is 1 cm/month, we can simply add \( t \) to the initial height.
