Question

Directions: Simplify the following monomials (if possible).

Answer 1

6) it’s -11a^2b^(because they have the same letters plus both of them have squares and if there isn’t any number in the on the other side it means that it is 1)
7)1mn(subtract and then put the sign of the bigger number)
9)-50xy^2(addition)
10)-49ac^d(subtract and put the sign of the bigger number)
11) 7y + 6z(arrange them first and then add and subtract.)
(Hope this helps)
