Answer:
In short your answer is Options 2, 3 and 4.
Step-by-step explanation:
Option 1:
If you distribute 4 among everything in the parenthesis, you'll get 4 × x = 4x and
4 × 4 = 16. Essentially your answer will be
4x + 16, so this is not equivalent.
Option 2:
If you combine like terms 2x and 2x, you'll get 4x, then add 3 and 1 to get 4. Your answer will be 4x + 4. So this is equivalent.
Option 3:
If you distribute 2 among everything in the parenthesis, you'll get 2 × 2x = 4x and 2 × 2 = 4. Essentially your answer will be 4x + 4, so this is equivalent.
Option 4:
If you combine like terms 3x and x, you'll get 4x. So essentially your answer is
4x + 4, so this is equivalent.
Hope this helped :)
