Question

`10-5\left(9n-9\right)`

Answer 1

To simplify the expression 10 - 5(9n - 9), we first distribute the -5 to each term inside the parentheses:

10 - 5(9n - 9) = 10 - 5 * 9n + 5 * 9

Next, we simplify the multiplication:

10 - 45n + 45

Finally, we combine like terms:

55 - 45n

So, the simplified expression is 55 - 45n.
