Answer:
There will be four terms before combining like terms. Six when multiplying a monomial by a trinomial. And two trinomials will be nine terms.
The answer is the second one, Balance.
1. It meant that they are flat, unlike 3-dimensional objects: you can place them on a table and one of their sides will be a like. This also means that they cannot show depth very well.
2: It means that it can create an illusion or an abstraction, that we can consider aesthetic. For example, while we enjoy drawings, which are 2-dimensional, it could be that we would consider their 3d-version scary
3: the limitation is that they cannot show depth. For example, an orange appears as a circle, not a sphere: so a part of the information is missing.
856 + (19 - 3 - (6 + (5 - 3) - (2 + 1) + (5 - 3) ) ) = 856 + (16 - (6 + 2 - 3))
= 856 + (16 - 5)
= 856 +11
= 867
