2x + 22 = 4(x + 3)<br> Please help me
Annette [7]

Answer: x=5

Step-by-step explanation:

2x+22=4(x+3)

Now intractable 2x from both sides

22=2x+12

Now subtract 12 from both sides

10=2x

When a certain tree was first planted, it was 4 feet tall, and the height of the tree increased by a constant amount each year f
MA_775_DIABLO [31]

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.
