Question

After “m” months the height of a plant is (10 + 3m) millimeters. How tall is the plant for 8 months? 3 years?

Answer 1

8 months = 34 millimeters
EXPLANATION:
You have to plug in the number 8 as “m” in the equation then solve. 10 + 3(8)

3 years = 118 millimeters
EXPLANATION:
3 years converted to months would be 12x3 which equals 36. Then put it into the equation 10 + 3(36) and you do multiplication first.

Answer 2

Answer:

8 months = 34 mm

3 years = 118 mm

Step-by-step explanation:

The height of the plant is given by

h = 10+3m where m is the months

At 8 months

 h = 10 +3(8)

    = 10+24

     = 34 mm

At 3 years

 we need to conver years to months

3 years* 12 months / 1 year = 36 months

h = 10 +3(36)

  = 10 +108

  = 118 mm
