Question

(4,7a + 2,2c) • ( - 2) - (9,6a - 4,4c) =

Answer 1

(4,7a + 2,2c) • ( - 2) - (9,6a - 4,4c) =-9,4а-4,4с-9,6а+4,4с=-19а

Answer 2

(4,7a + 2,2c) • ( - 2) - (9,6a - 4,4c) =-9,4a-4,4c-9,6a+4,4c=-19a

Answer 3

To simplify the given expression, let's distribute the scalar (-2) to each term inside the parentheses and then combine like terms:

(4,7a + 2,2c) • (-2) - (9,6a - 4,4c)

= (-2) * 4,7a + (-2) * 2,2c - (9,6a - 4,4c)

= -9,4a - 4,4c - 9,6a + 4,4c

Now, let's combine like terms:

= (-9,4a - 9,6a) + (-4,4c + 4,4c)

= -18a + 0c

Therefore, the simplified expression is -18a.
