Answer 3

To simplify the expression, let's perform the operations step by step:

Step 1: Simplify the inner expression within the parentheses.

(-5 + а) becomes just "а" because the negative sign in front of (-5) changes the sign of each term inside the parentheses.

Step 2: Substitute the simplified expression back into the original expression.

-(-5 + а) - 7.2 = -(а) - 7.2

Step 3: Simplify further.

Now, we have a negative sign in front of "а" and a subtraction of 7.2. The expression is already simplified as much as possible, so the final result is:

-(а) - 7.2
