Question

упростите выражение: 2/5*(5x-10y)-1/4*(8x+16y)

Answer 1

 Раскрываем скобки, ставим знак в зависимости от предыдущего, используя закон умножения

A(d+c) = ad+Ac

2х - 4у - 2х - 4у =0

Answer 2

я же решу по действиям:

1) 2\5*(5х-10у)=  2х- 4у

2) 1\4*(8х+16у)= 2х + 4у

3) 2х-4у-2х-4у=-8у

Ответ: -8у

For your query, I will try to simplify the expression and show you the steps. The expression is:

$$\frac{2}{5}(5x-10y)-\frac{1}{4}(8x+16y)$$

First, we distribute the fractions to the terms inside the parentheses:

$$\frac{2}{5}\times 5x - \frac{2}{5}\times 10y - \frac{1}{4}\times 8x - \frac{1}{4}\times 16y$$

Then, we simplify the fractions by canceling out the common factors:

$$2x - 4y - 2x - 4y$$

Next, we combine the like terms by adding or subtracting the coefficients:

$$0x - 8y$$

Finally, we simplify the expression by removing the zero term:

$$-8y$$

Therefore, the simplified expression is:

$$-8y$$

I hope this helps you. If you have any other questions or requests, please let me know.Ответь+подробно.+упростите+выражение:+2/5*(5x-10y)-1/4*(8x+16y)
