  1. Use distributive property. Multiply 9 by 9x first to get 81x.
  2. Next, multiply 9 by 2y to get 18y.
  3. Now you have 81x + 18y - 6.
  4. Since the problem says to write an equivalent expression, that is your answer.

81x + 18y - 6

Answer:


\Longrightarrow: \boxed{\sf{81x+18y-54}}

Explanation:

Use the distributive property.

⇒ A(B+C)=AB+AC

9(9x+2y-6)


\Longrightarrow: \sf{9*9x+9*2y+9(-6)}

Multiply.

Solve.

9*9x=81x

2y+9(-6)

2y*9=18y

9*6=54

Rewrite the expression down.


\Longrightarrow: \boxed{\sf{81x+18y-54}}

  • Therefore, the correct answer is 81x+18y-54.

I hope this helps! Let me know if you have any questions.
