Answer: it will take 0.33 years for the heights to be the same.
Step-by-step explanation:
Let x represent the number of years it will take for both trees to be the same height.
Type A is 7 feet tall and grows at a rate of 2 inches per year. This means that the height of the tree after x years would be
2x + 7
Type B is 2 feet tall and grows at a rate of 17 inches per year. This means that the height of the tree after x years would be
17x + 2
For the heights to be the same, the number of years would be
17x + 2 = 2x + 7
17x - 2x = 7 - 2
15x = 5
x = 5/15
x = 0.33 years
