Answer:

A. 34 millimeters.

B. 118 millimeters.

Explanation:

We have been given that after m months the height of a plant is
10+3m millimeters.

To find the height of plant after 8 months we will substitute m=8 in our given expression.

$\text{The height of plant after 8 months}=10+3* 8$

$\text{The height of plant after 8 months}=10+24$

$\text{The height of plant after 8 months}=34$

Therefore, the height of plant after 8 months will be 34 millimeters.

B. Now let us find height of plant after 3 years.

First of all we will convert 3 years into months by multiplying 3 by 12 as 1 year equals to 12 months.

$\text{3 years}=3*12\text{ months}=36\text{ months}$

Now let us substitute m=36 in our given expression.

$\text{The height of plant after 36 months}=10+3* 36$

$\text{The height of plant after 36 months}=10+108$

$\text{The height of plant after 36 months}=118$

Therefore, the height of plant after 3 years (36 months) will be 118 millimeters.
