Width = 2,848 km = 2,848,000 m
2,848,000 m * 100 = 284,800,000 cm
If Europe and North America are moving apart at 2 cm per year:
284,000,000 : 2 = 142,400,000 years
Answer: The North Atlantic Ocean began to form 142,400,000 years ago.

svp [43]

Answer:

Option B) -9 is correct

The evaluated given expression when x=-3 is 2x+x=-9

Step-by-step explanation:

Given expression is 2x+x

Now to evalute the given expression when x=-3 as below :

2x+x when x=-3

That is put x=-3 in the given expression we get

2x+x=2(-3)+(-3)

=-6-3

=-9 ( adding the like terms here )

Therefore 2x+x=-9

The evaluated given expression when x=-3 is 2x+x=-9

Option B) -9 is correct
