What is the value of the expression when n=3? 6 (n2+2) / n

The value of the expression would be 22

Step-by-step explanation:

In order to find this, simply put 3 in for every value of n we see.

6 (n^2+2) / n

6 ((3)^2 + 2) / (3)

6 (9 + 2) / 3

6(11) / 3

66/3

22

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
