<span>212 -(72 divided by 2)=</span>212-36=176
Simple....
you have: 4(x+7)
To simplify it..distribute..
4(x+7)
4*x=4x
and
4*7=28
Leaving you with...
4x+28
As we can see B is 4x+28
Thus, your answer.
∩ stands for the intersection of the two arrays think a venn diagram in this it would be three
<span>∪ stands for objects that belong to either set
</span>
It would be A <span>∪ B because that set shows objects from both sets
If i'm wrong sorry its been a while since I've practiced or learned it</span>
