I really need the explanation

Answer : The two correct options are,

3.4a + 5.6b

5.6b + 3.4a

Step-by-step explanation :

The given expression is:

(-2.4a - 1.8b) - (-3.8a - 4.4b) + (2.0a + 3.0b)

First we have to open the brackets.

⇒ -2.4a - 1.8b + 3.8a + 4.4b +2.0a + 3.0b

Now keep like terms together.

⇒ -2.4a + 3.8a +2.0a + 3.0b - 1.8b + 4.4b

By subtraction or addition, we get:

⇒ 3.4a + 5.6b

or,

⇒ 5.6b + 3.4a

Hence, the expressions that equivalent to the given expression are, 3.4a + 5.6b and 5.6b + 3.4a
