Subtract these polynomials.
(3x2 + 3x + 3) - (x2 + 2x + 3) =
a. 2x2 + x
b. 2x2 + 5x
c. 2x2 + 5x + 6
d. 2x2 + x + 6

for b its (t) and c its (d)

step-by-step explanation:

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.
