Answer:
3*w
Step-by-step explanation:
Kamilah now weighs the triple of what she weighed on her first birthday. That means we need to multiply the first weight by 3. As the first weight is w, she now weighs 3*w.
Another possible expression is to sum 3 times w, that is w + w + w (it's equal to 3*w).
The scale factor's 3 since 12 and 4 can be divided by 3 and -6 and -2 can also be divided by 3.
18/13 or in simplified form, 1 and 5/13.
