Answer:
Size of each group = 
Step-by-step explanation:
Total number of paint brushes = x
Since each the three groups are equally sized, to get the number of paintbrushes in a group, we will have to divide the total number of paint brushes by 3
∴ We have, number of paint brushes in a group = 
= 
this is also the same thing as saying
×
This shows that the size of the new group is the same as
the size of the original group
(x^2)+4x-12=48
I Hope this is what you were looking for. If it isn't this just plug it in
x=6
are your O's different sizes? or is it just my eyes?
The answer that I got was y=105
Hope this helps!
I believe the answer is 60
