Apologies for the incorrect response. Let's try again.

Lucinda could have written the expression as:

9 + 3(5 - a) - 7a

Expanding the parentheses:

9 + 15 - 3a - 7a

Combining like terms:

24 - 10a

So, the correct expression that Lucinda could have written is 24 - 10a.

Answer 4

wrong

Answer 5

Apologies for the mistake. Let's try again.

Lucinda could have written the expression as:

9 + 3(5 - a) - 7a

Expanding the parentheses:

9 + 3(5) - 3(a) - 7a

Simplifying inside the parentheses:

9 + 15 - 3a - 7a

Combining like terms:

24 - 10a

Therefore, the correct expression that Lucinda could have written is 24 - 10a.
