Evaluate 8x2 + 4x + 3 for x = 5

The correct answer is: 163

To find the value of an expression, you substitute the given value for the variable and solve the resulting equation. In this case, plugging in x = 5 gives us 8(5)^2 + 4(5) + 3 = 8(25) + 20 + 3 = 163. Option B is incorrect because the value of 8(5)^2 would already equal 100, so adding 4(5) and 3 to it would result in a value greater than 100. Option C is incorrect because it does not account for the variable x, which is necessary in the expression. Option D is incorrect because it only accounts for the last term, 3, and does not take into account the other terms in the expression. Therefore, option A is the correct answer.
