10.) Write an equivalent expression to d+ d + d + W+W+W+W

3d + 4w

Step-by-step explanation:

Since there are multiple of each variable, we can add like terms.

There are 3 d's, so adding these together gets you 3d

There are 4 w's, so this is equal to 4w.

Now, add these together to get the equivalent expression:

3d + 4w is the expression
