Omg help me asap my lesson is timed!

-27w^9

Step-by-step explanation:

Multiply

-3w^8 × 9w

Step 1:

-3 × 9

= -27

Step 2:

w^8 × w¹

Using the law of indices

w^8 × w¹

= w^(8+1)

= w^9

-3w^8 × 9w

= -27w^9

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.
