Which expression is equivalent to 9 (w+8) ?

72W

9W+72

9W+8

17W

9W + 72

Step-by-step explanation:

using the distributive property, you would multiply both the w and the 8 by 9 to obtain 9*w and 9*8. 9*w + 9*8 = 9w + 72.

This works because if you have 9 of (w+8), you have 9 w's and 9 8's. Adding these up is simply multiplying 9 by w (since there are 9 w's) and 9 by 8 (since there are 9 8's).

We can apply the distributive property to 9 (w + 8) to find an equivalent expression.

9w + 72

The equivalent expression is the 2nd option, or 9w + 72,
