Subtract (5/t^2) - (4/t+1)

4t²+5t+5/t³+t²

Step-by-step explanation:

(5/t^2) - (4/t+1)

Using LCM

5(t+1)-4(t²)/(t²)(t+1)

5t+5-4t²/t³+t²

-4t²+5t+5/t³+t²

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.
