Sagot :
- Use distributive property. Multiply 9 by 9x first to get 81x.
- Next, multiply 9 by 2y to get 18y.
- Now you have 81x + 18y - 6.
- Since the problem says to write an equivalent expression, that is your answer.
81x + 18y - 6
Answer:
[tex]\Longrightarrow: \boxed{\sf{81x+18y-54}}[/tex]
Step-by-step explanation:
Use the distributive property.
⇒ A(B+C)=AB+AC
9(9x+2y-6)
[tex]\Longrightarrow: \sf{9*9x+9*2y+9(-6)}[/tex]
Multiply.
Solve.
9*9x=81x
2y+9(-6)
2y*9=18y
9*6=54
Rewrite the expression down.
[tex]\Longrightarrow: \boxed{\sf{81x+18y-54}}[/tex]
- Therefore, the correct answer is 81x+18y-54.
