Let's solve the equation step by step:

Given: $4x + 4 = 4^2$

1. First, simplify the right-hand side: $4^2 = 16$ So, the equation becomes: $4x + 4 = 16$

2. Subtract 4 from both sides to isolate the term with $x$: $4x = 16 - 4$ $4x = 12$

3. Divide both sides by 4 to solve for $x$: $x = \frac{12}{4} = 3$

Thus, the solution is: $x = 3$

However, none of the answer choices match this result. Could you clarify if the equation was intended to be different, or if there’s a particular context for these answer choices?

Let me know if you'd like to go over this or have any clarifications!

Here are 5 questions that can expand on this:

1. How would the solution change if the constant on the right side was 20 instead of $4^2$?
2. What happens to the solution if the coefficient of $x$ is halved?
3. How do you solve the equation if there’s a fractional power involved?
4. Can you express $4^2$ as a logarithmic equation?
5. How does solving this equation compare to solving a quadratic equation?

Tip: Always simplify powers and constants first before isolating the variable for easier calculations!
