Verified Answer :

A20+10h

You know that you have 20 inches to start with, then it will grow 2h four times, or 8h total. Then it will grow h 2 times, or 2h. You add the 20, 8h, and 2h, to get 20+10h.

Hope this helps!

Answer:

Option A is correct

20+10h

Step-by-step explanation:

As per the statement:

A plant is 20 inches tall.

It is also given that:

If the plant grows 2h inches each week for the next 4 weeks,

⇒\((2h) \cdot 4 = 8h\)

and

h inches for each of the 2 weeks .

⇒\((h) \cdot 2 = 2h\)

Then,  every 2 weeks after that, another 2h.

⇒ in 6 weeks, a total of 10h inches height of the plant grows

We have to find the expression shows the height of the plant in inches after 6 weeks.

Initially, a plant is 20 inches tall.

in 6 week,  a total of 10h inches height of the plant grows

⇒the height of the plant in inches after 6 weeks = 20 + 10h

Therefore, the expression shows the height of the plant in inches after 6 weeks is, 20+ 10h
