The inequality expression for the number of years when tree will be atleast 20 feets tall is x ≥14
- Growth rate = 1.3 feets per year
The height of the tree after x years can be represented as a linear equation thus :
<u>Number of years when the tree will be 20 feets tall</u> :
- 20 = 2 + 1.3x
- 20 - 2 = 1.3x
- 1.3x = 18
- x = 13.84
<u>The tree would be atleast 20 feets tall in 14 years x this can be expressed thus </u>
