Question

Упрости выражения 25а+(a-b)×6
90x-(5x+7x) 14×(x+a)-13x​

Answer 1

Here are the solutions to each of the expressions:

25a + (a - b) * 6

To solve this expression, you first need to distribute the 6 to the (a - b) term, which gives you:

25a + 6a - 6b

Next, you can combine the two terms with a in them:

31a - 6b

So the simplified expression is: 31a - 6b.

90x - (5x + 7x)

To solve this expression, you need to simplify the parentheses first by combining the like terms:

90x - 12x

Next, you can combine the two terms with x in them:

78x

So the simplified expression is: 78x.

14(x + a) - 13x

To solve this expression, you first need to distribute the 14 to the (x + a) term, which gives you:

14x + 14a - 13x

Next, you can combine the two terms with x in them:

x + 14a

So the simplified expression is: x + 14a.

Answer 2

Ответ:

1) 25а+(а-b)*6

25a+a-b*6

25a+a-6b

26a-6b

2) 90x-(5x+7x)

90x-12x

78x

3) 14*(x+a)-13x

14*x+a-13x

14x+a-13x

x+a

Фух, вроде правильно
