Preform the operation
(−4x 2 +2)−(−7x 2 +10x+1)

-4x + 1

Step-by-step explanation:

( −4x 2 +2 ) − ( −7x 2 + 10x + 1 )

(-4x) (2) + 2 + -1 (-7x) (2) + -1 (10x) + -1 (1)  <--- First let's distribute

-8x + 2 + 14x + -10x + -1

(-8x + 14x + -10x) + (2 + -1)   < Now combine like terms

-4x + 1   <--- Final Answer :)

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.
