Question

describe each expression. the expression 2x - 4 means 4 less than the sum product difference 2 and a number. the expression 2(x - 4) means 2 more than the of a number and 4.

Explanation:

Step1: Analyze \(2x - 4\)

In \(2x-4\), \(2x\) is the product of \(2\) and \(x\) (a number), and then we subtract \(4\). So \(2x - 4\) means \(4\) less than the product of \(2\) and a number.

Step2: Analyze \(2(x - 4)\)

In \(2(x - 4)\), first we find the difference \(x-4\) (difference of a number \(x\) and \(4\)), and then we multiply the result by \(2\). So \(2(x - 4)\) means \(2\) times the difference of a number and \(4\).

Answer:

For \(2x - 4\): product
For \(2(x - 4)\): difference
