a) is the right answer because if for example x=1 then 9(6+1)= 9.7=63 and 9.6+9.1=54+9=63. That means these expressions are equivalent.

Final answer:

The expressions that are equivalent are: 9(6 + x) and 9.6+9.x, and 6.x+3 and 6. (x+3). To determine if expressions are equivalent, we can simplify and compare them.

Step-by-step explanation:

The expressions that are equivalent are:

  • a) 9(6 + x) and 9.6+9.x
  • c) 6.x+3 and 6. (x+3)

To determine if two expressions are equivalent, we can simplify and compare them. In both cases, we distribute the 9 and 6 respectively to both terms inside the parentheses. This results in the same expression and shows that they are equivalent.
