Answer 1

Ответ:

1)a*(10+4-4)

Пошаговое объяснение:

Answer 2

1. 10a + (4 - 4a)

First, distribute the 10a into the parentheses:

10a + 4 - 4a

Now, combine like terms by adding the coefficients of 'a':

(10a - 4a) + 4

= 6a + 4

The simplified expression is 6a + 4.

2. -(4b - 10) + (4 - 5b)

Start by simplifying the expression inside the first set of parentheses by distributing the negative sign:

-4b + 10 + (4 - 5b)

Next, simplify the expression inside the second set of parentheses:

-4b + 10 + 4 - 5b

Now, combine like terms by adding the coefficients of 'b':

(-4b - 5b) + 10 + 4

= -9b + 14

The simplified expression is -9b + 14.

3. (c - 5d) - (-d + 5c)

Apply the distributive property by multiplying -1 to the expression inside the second set of parentheses:

(c - 5d) + (d - 5c)

Now, rearrange the terms to group like terms together:

c + (-5d + d) + (-5c)

Combine like terms by adding the coefficients:

c - 4d - 5c

Simplify the expression:

-4d - 4c

The simplified expression is -4d - 4c.
