I want to say either rectangular prisim or triangle pyrimad
Example: 
We can see that there is more than one number with the variable x, therefore, we say they're ''like terms'' and because of that they can be summed. We do this with all of the other numbers with similar variables. If no numbers with similar variables are left, like 4a, you don't do anything but write them as they are. You can also see that 8 and 9 can also be summed because neither of them has a variable, therefore they're similar.
In this step, you just do the operation with the numbers and keep the same variable.


since there are not more numbers similar in variables, this operation is done.

A because we all know the intersection of sin is always in (0,0) but in this case it is different
Answer: idk the answer but i can tell u that u are trying to find the value of the symbols and the numbers :)
