Which of the following expressions is equivalent to (x+3)²-4(x+3)-12 ? A (x + 2)(x-6)
B (x + 3)(x - 4)
C (x + 5)(x - 3)
D (x + 9)(x + 1)

C

Step-by-step explanation:

(x+3)(x+3) - 4x - 12 - 12

x² + 3x + 3x + 9 - 4x - 24

x² + 2x - 15

(x + 5) (x - 3)

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.
