When 63x3y + 105x2y is divided by -7xy, the quotient is . if this quotient is divided by , the result is 3x + 5.

   -9x^2 - 15x.

   -3x.

Step-by-step explanation:

The first quotient is -9x^2 - 15x.

To find the second result we divide the above  by 3x + 5:

          -3x

3x + 5) -9x^2 - 15x

           -9x^2 - 15x

The result is -3x.

the probability is 0

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.
