The product of a number x and four decreased by twelve. Which of the following is an expression for the statement above?

Explanation

The correct expression for the statement 'The product of a number x and four decreased by twelve' is 4x - 12. This is because 'the product of a number x and four' translates to multiplying x by 4, resulting in 4x. 'Decreased by twelve' means subtracting 12 from this product, leading to the expression 4x - 12.Option A is incorrect because it adds 12 instead of subtracting, resulting in 4x + 12. Option B is incorrect because it suggests adding 12 to x before multiplication, resulting in 4(x + 12). Option C is incorrect because it suggests subtracting 12 from x before multiplication, resulting in 4(x - 12).
