The plants will be exactly the same height during week

Answer 1

4.

To find out when the plants will be the same height, set the two equations equal to each other:

3x + 8 = 2x + 12

Subtract 2x from both sides:

x + 8 = 12

Subtract 8 from both sides:

x = 4

Therefore, the plants will be exactly the same height during week 4.
