Question

(3x + 7y)c – y( 4x + 7c)+ 2x(4y – 2c)​

Answer 1

Ответ:

Пошаговое объяснение:

(3x + 7y)c – y( 4x + 7c)+ 2x(4y – 2c)​ =

3хс + 7ус - 4ху - 7ус + 8ху - 4хс =

-хс + 4ху = -х (с + 4у)

Answer 2

To simplify the expression (3x + 7y)c - y(4x + 7c) + 2x(4y - 2c), you can use the distributive property to expand and then combine like terms:

(3x + 7y)c - y(4x + 7c) + 2x(4y - 2c)

First, distribute the constants c, -y, and 2x to the terms inside the parentheses:

3xc + 7yc - 4xy - 7cy + 8xy - 4xc

Now, you can group like terms:

(3xc - 4xc) + (7yc - 7cy) + (-4xy + 8xy)

Simplify further:

-xc + 0 + 4xy

Now, combine the like terms:

4xy - xc

So, the simplified expression is 4xy - xc.
