Question

(1,2a-4)+(40-4,8a)==

Answer 1

1,2а-4+40-4,8а= 1,2а-4,8а+40-4=-3,6а+36

Answer 2

To solve the expression (1,2a-4) + (40-4,8a), we can first simplify it by combining like terms and performing the addition.

(1,2a-4) + (40-4,8a)

First, distribute the addition operation to both terms within the parentheses:

1 + 2a - 4 + 40 - 4,8a

Now, combine the constants (the numbers without 'a'):

(1 - 4 + 40) + (2a - 4,8a)

Combine the constants on the left side:

(37) + (2a - 4,8a)

Now, combine the 'a' terms on the right side:

(37) + (-2.8a)

Now, you have a simplified expression:

37 - 2.8a

So, (1,2a-4) + (40-4,8a) simplifies to 37 - 2.8a.
