Question

4) Which expression is equivalent to 3x + 5x? X + 8 8x + 2. 8x. 2x​

Answer 1

Answer:

8x

Step-by-step explanation:

3x + 8x are like terms which means they have the exact same variable.

To add like terms we add the coefficients which are 3 and 5.  

3 + 5 = 8  

We have 8 x's. So 3x + 5x = 8x.

In order to add terms, the variable part has to be exactly the same.

It's like saying 3 balls + 5 balls = 8 balls.
