Jaleel and lisa are simplifying the expression 2(x-2)+2 as shown. whose method is correct and why?

The correct expression is 2x-2.

Step-by-step explanation:

To simplify this expression, we first use the distributive property:

2(x-2)+2

2(x)-2(2)+2

2x-4+2

Lastly we combine like terms:

2x-2

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.
