Question: 1 / 400

What is the numerical value of the expression 4x + 8 when x=12?

0

8

16

64

To find the numerical value of this expression, we substitute x=12 into the equation. This gives us

4(12) + 8 = 48 + 8 = 56.

So, 4x + 8 when x=12 is equal to 56. Option A is incorrect because it does not account for the value of x. Option B is incorrect because it only includes the constant term, 8, and does not account for the variable x. Option C is incorrect because it only includes the coefficient of x, 4, and does not account for the constant term. Therefore, the only correct answer is option D - 64. It is important to correctly substitute the given value for x in the equation to find the numerical value of the expression.
