The answer is - c lol i didnt give explanation

Answer 2

Answer: 2x + 4x = (2 + 4)x = 6x

Explanation:

The expression 2x + 4x represents the cost of buying the same number of cases of spring water and sparkling water. To express the total cost, we need to add the cost of buying the two types of water.

Since the expression 2x represents the cost of buying x cases of spring water, and 4x represents the cost of buying x cases of sparkling water, the total cost can be expressed as:

2x + 4x = (2 + 4)x = 6x

Therefore, the total cost of buying x cases of spring water and sparkling water can be expressed as 6x.

Alternatively, you can think of it as buying x cases of spring water at a cost of 2x dollars and x cases of sparkling water at a cost of 4x dollars. So the total cost is (2x+4x) dollars which is 6x dollars.
