Answer 3

a) 2а + (3а - 8б)

To expand the brackets, we can apply the distributive property, which states that multiplying a number or expression by a sum or difference is the same as multiplying it by each term in the sum or difference separately and then adding or subtracting the results.

In this case, we have:

2а + (3а - 8б)

First, let's distribute the 2а to each term inside the brackets:

2а + 3а - 8б

Now, we can simplify by combining like terms:

(2а + 3а) - 8б = 5а - 8б

So, the expression 2а + (3а - 8б) simplifies to 5а - 8б.

b) 6(с + 1) - 6с - 5в

Using the same distributive property, we can expand the brackets:

6(с + 1) - 6с - 5в

First, let's distribute the 6 to each term inside the brackets:

6с + 6 - 6с - 5в

Now, we can simplify by combining like terms:

(6с - 6с) + 6 - 5в = 0 + 6 - 5в = 6 - 5в

So, the expression 6(с + 1) - 6с - 5в simplifies to 6 - 5в.

c) (5 - 2х) - (7 + 10х)

Again, using the distributive property, we can expand the brackets:

(5 - 2х) - (7 + 10х)

First, let's distribute the negative sign to each term inside the second set of brackets:

(5 - 2х) - 7 - 10х

Now, we can simplify by combining like terms:

5 - 2х - 7 - 10х = -2х - 10х + 5 - 7 = -12х - 2

So, the expression (5 - 2х) - (7 + 10х) simplifies to -12х - 2.

d) -2(2р - 1) + 4д

Applying the distributive property to expand the brackets:

-2(2р - 1) + 4д

First, let's distribute the -2 to each term inside the brackets:

-4р + 2 + 4д

Now, we can simplify by combining like terms:

-4р + 4д + 2

So, the expression -2(2р - 1) + 4д simplifies to -4р + 4д + 2.

e) 33 - 8(11п - 1) - 2п

Expanding the brackets using the distributive property:

33 - 8(11п - 1) - 2п

First, let's distribute the -8 to each term inside the brackets:

33 - 88п + 8 - 2п

Now, we can simplify by combining like terms:

33 + 8 - 88п - 2п = 41 - 90п

So, the expression 33 - 8(11п - 1) - 2п simplifies to 41 - 90п.
