Answer:
1= C. 20h
2= A. 12n
Step-by-step explanation:
1= 20(3)=20x3=60
2= you put your digits before variables. in this case your digit is 12 and you variable is n. so it would be 12n. also because the product is multiplication and a variable (which represents an unkown number) directly next/behind a digit (in this case 12) means to multiply.
