What is the additive inverse of the polynomial 9xy^2 + 6x^2y – 5x^3?
a.9xy2 – 6x2y + 5x3
b. 9xy2 – 6x2y – 5x3
c. 9xy2 + 6x2y + 5x3
d. 9xy2 – 6x2y + 5x3

The answer is B.

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.

he has now walked a total of what?

if i know what this is maybe i can
