Answer: 3 weeks
Step-by-step explanation:
We have to note firstly that 12 inches = 1 foot.
The equation given to represent the height in the question, h = 3w + 3.
The number of weeks that it will take the plant to reach one foot will then be:
h = 3w + 3
12 = 3w + 3
3w = 12 - 3
3w = 9
w = 9/3
w = 3
It'll take 3 weeks
