What is 3 times the square root of 12 plus 4 times the square root of 3 in simple form.

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

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.
