Answer 1

Пошаговое объяснение:

если перед дужками стоит знак +, то содержимое так и переписываем, а если знак - то все знаки меняем на противоположные

а. =а-б-с

б. =-в+б+с

Answer 2

Let's simplify the given expressions:

A) + (a - b - c):

To simplify this expression, we start by removing the parentheses:

A) + (a - b - c) = A + a - b - c

Next, we can combine like terms:

A + a - b - c = (A + a) - b - c

So the simplified expression is (A + a) - b - c.

B) + (-a + b + c):

Similarly, we remove the parentheses:

B) + (-a + b + c) = B - a + b + c

Again, we combine like terms:

B - a + b + c = (B - a) + b + c

So the simplified expression is (B - a) + b + c.

Note that A and B represent some unknown values or variables, and we have simply rearranged the terms in each expression without assigning specific values to them.
