Answer:
1. $685 - ( $273 + $119 )
2. $273 + $119
3. $293
Step-by-step explanation:
It is given that,
Vanessa initially has $685.
Vanessa spent $273.
Vanessa donated $119.
1. So, we get that, the expression for the money she was left with is,
Vanessa is left with $685 - ( $273 + $119 ).
2. Since, before subtracting the amount Vanessa spent, we need to calculate the total expense she had.
Thus, the hidden calculation is $273 + $119.
3. We have the problem given by, $685 - ( $273 + $119 ) = $685 - $392 = $293.
Thus, Vanessa is left with $293.

Answer:
a = 5, b = -12
Step-by-step explanation:
By basic factoring, you get 9 - 12i + . Since
is simply -1, the expression evaluates to 9 - 12i - 4, which is 5 - 12i.
