Answer:

Option D is the correct answer.

Step-by-step explanation:

Initial height = 4 feet

Given that the height of the tree increased by a constant amount each year for the next 6 years. At the end of the 6th year, the tree was 1/5th taller than it was at the end of the 4th year.

Let the rate of growing each year be g.

After 6 years height of tree = 4 + 6g

After 4 years height of tree = 4 + 4g

At the end of the 6th year, the tree was 1/5th taller than it was at the end of the 4th year.

That is

                4+6g=4+4g+\frac{4+4g}{5}\\\\4+6g=\frac{20+20g+4+4g}{5}\\\\20+30g=24+24g\\\\6g=4\\\\g=\frac{2}{3}ft/year

Option D is the correct answer.

Write a short paragraph discussing the reasons why someone should make a will.
LuckyWell [14K]
When someone dies everyone wonders what will happen to all of their possessions. If the person had a will then everyone will know what they have to keep. If the person did not have a will then no one will know what to keep and what not to keep. That can cause problems among family and friends. To keep the peace and sentimental value in balance a will is very important to make.

When you figure out what y is you plug it in and do PEMDAS. 
But if it doesn't tell you what y is then the equation I wrote is the answer.
