Question

3) 14x+y:(-7xy);4) 72cd : (9cd2);5​

Answer 1

Ответ:

1)  14x+y:(-7xy)

14 x -   y/7xy

14 x -   1/7x

98x^2-1/7x

2) 72cd : (9cd2)

72cd / (18cd)

4

Answer 2

Ответ:

1)98x^2-1/7x ("/", это дробь если что)

Решение 14х+у:(-7ху) запишим деление в виде дроби, то есть 14х-у/7ху. Сократим дробь на у 14х-1/7х. Запишим все числители над общим знаменателем ответ :98х^2-1/7х

2)ответ 8 просто вычесли :)

Удачи)

Answer 3

It looks like you've provided some expressions with colons in between them. It seems like you might be asking for simplifications or calculations involving these expressions. Let's go through each of them step by step:

3. $\frac{14x + y}{-7xy}$: To simplify this expression, you can factor out a common term from the numerator: $\frac{y(14x + y)}{-7xy}$ Now, you can cancel out a factor of $y$ from the numerator and the $xy$ terms from the denominator: $\frac{14x + y}{-7x}$ This is the simplified expression.

4. $\frac{72cd}{9cd^2}$: First, simplify the constants in the numerator and denominator: $\frac{8 \cdot 9 \cdot cd}{9 \cdot cd^2}$ Cancel out a factor of $9$ from the numerator and denominator: $\frac{8 \cdot c}{d}$ This is the simplified expression.

5. It seems like you've only provided "5" without an associated expression or operation. If you provide the expression you'd like to simplify or calculate, I'd be happy to help.

Please let me know if you have any specific questions or if you'd like further assistance with these expressions!
