Question

( expressions)
A plant grew 2 cm every day for d days. How much did it grow?

Answer 1

trick question it grew exactly 2 cm since we don't know the value of d there can't be an outcome

Answer 2

It will grow '2d'

Explanation:

Given,

The increment per day in the height of plant = 2 cm,

Total number of days = d,

Thus, the growth of plant in d days = growth of plant per day × number of days

`=2d`

Hence, the required expression that shows the growth of plant is,

`2d`
