Який з поданих виразів одержимо розкривши дужки. -(а-b)+(-p)? який з поданих виразів одержимо спростивши вираз.(p-2)-(p-K+4)(1-pпри якому з поданих значень х рівняння 7.х=-21 перетворюється у правильну рівність.? якщо в рівнянні х+4(-4)=2 доданок -4 перенести з лівої частини в праву то одержимо рівняння яке?

Answer 1

Ответ:

1) -а+b-p

2) p-2-p+K-4 = K-6

3) якщо х буде дорівнювати -3

4) х+4 = 6

Answer 2

Expression: -(a-b) * (-p)

To expand the expression -(a-b) * (-p), we can apply the distributive property of multiplication over addition/subtraction.

The distributive property states that for any real numbers a, b, and c, the expression a * (b + c) is equal to a * b + a * c.

In this case, we have -(a-b) * (-p). To expand it, we can distribute the negative sign to both terms inside the parentheses:

-(a-b) * (-p) = -a + b * (-p)

So, the expanded expression is -a + b * (-p).

Simplifying the expression: (p-2) - (p-K+4) * (1-p)

To simplify the expression (p-2) - (p-K+4) * (1-p), we can apply the distributive property and combine like terms.

First, let's distribute the (p-K+4) term to (1-p):

(p-2) - (p-K+4) * (1-p) = (p-2) - (p-K+4-p*(p-K+4))

Next, let's simplify the expression by combining like terms:

(p-2) - (p-K+4-p*(p-K+4)) = p - 2 - p + K - 4 - p*(p-K+4)

Now, let's distribute the p to the terms inside the parentheses:

p - 2 - p + K - 4 - p*(p-K+4) = p - 2 - p + K - 4 - p^2 + pK + 4p

Finally, let's combine like terms:

p - 2 - p + K - 4 - p^2 + pK + 4p = -p^2 + (pK + 5p + K - 6)

So, the simplified expression is -p^2 + (pK + 5p + K - 6).

Solving the equation: 7x = -21

To solve the equation 7x = -21, we need to isolate the variable x.

Dividing both sides of the equation by 7, we get:

7x / 7 = -21 / 7

Simplifying, we have:

x = -3

So, the solution to the equation 7x = -21 is x = -3.

Transferring the term -4 from the left side to the right side of the equation x - 4(-4) = 2

To transfer the term -4 from the left side to the right side of the equation x - 4(-4) = 2, we can use the property of equality that allows us to add or subtract the same value from both sides of an equation.

Starting with the equation x - 4(-4) = 2, we can simplify the expression on the left side:

x + 16 = 2

To transfer the term -16 to the right side, we subtract 16 from both sides:

x + 16 - 16 = 2 - 16

Simplifying, we have:

x = -14

So, transferring the term -4 from the left side to the right side of the equation x - 4(-4) = 2 results in the equation x = -14.
