Question

(xy-2x+5y)•3+2•(2xy-3x-6y)=?​

Answer 1

Ответ:

Пошаговое объяснение:

3xy - 6x + 15y + 4xy - 6x - 12y = 7xy - 12x + 3y

Answer 2

(xy-2x+5y)•3+2•(2xy-3x-6y) = 3ху-6х+15у+4ху-6х-12у = 7ху-12х+3у

Answer 3

Let's simplify the expression:

(xy - 2x + 5y) * 3 + 2 * (2xy - 3x - 6y)

First, let's distribute the multiplication:

3xy - 6x + 15y + 4xy - 6x - 12y

Combine like terms:

(3xy + 4xy) + (-6x - 6x) + (15y - 12y)

7xy - 12x + 3y

Therefore, the simplified expression is 7xy - 12x + 3y.
