15 ptss easy i promise for ! the distance from newtown to oldtown on the highway is (6x2 + 2x – 2) miles. using the back roads, the distance is (5x2 – 8x – 6) miles. how many miles shorter is the second route? a.)11x2 + 10x – 8 b.)–x2 – 6x + 4 c.)x2 + 10x + 4 d.)x2 – 6x – 8

For this case we have to subtract the two distances (subtract the polynomials) and the difference will be given by the shorter miles of the second route.

Taking into account that:

Adding similar terms:

So, the correct option is C

Option C

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.
