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>

Answer:
I think you are correct.
Step-by-step explanation:
I hope this helps you. Just stick to your instincts.
The perimeter of a square is a^2. In this case a= (4x-2y) so a^2=(4x-2y)^2 , a^2={16(x)^2-16xy+4(y)^2}
