Question

PLEASE HELP

Answer 1

1. A. y and 1.2y are like terms. c they both contain the same term (y) and can therefore be combined.

2. B. 12x+11 (you have to combine the like terms)

3. 15y+18-4
C. 15y+14 (you must distribute the 3 to inside the parentheses, so 3×5y and 3×6)

4. 9(9-3p) (you have to find a common factor between the terms, in this case 9, and you place it on the outside of the parentheses, while dividing that factor from those terms, which are placed in parentheses.
