Question

2*x-2*(8*x+4) при x=10​

Answer 1

Ответ:

-148

Пошаговое объяснение:

Подставим 10 вместо x:

2 * 10 - 2 * (8 * 10 + 4) = 20 - 2 * 84 = -148

Answer 2

1. Упрощаем выражение:

$\displaystyle \tt 2\cdot x-2\cdot(8\cdot x+4)=2x-16x-8=-14x-8$

2. Подставляем значение:

$\displaystyle \tt -14\cdot10-8=\bold{-148}$

Ответ: $\displaystyle \tt -148$

Answer 3

To find the value of the expression 2x - 2(8*x + 4) when x equals 10, you need to substitute x with 10 in the expression and then calculate the result.

Let's do the calculation step by step:

1. Replace x with 10 in the expression: 210 - 2(8*10 + 4)

2. Perform the operations inside the parentheses first: 210 - 2(80 + 4)

3. Continue simplifying: 20 - 2*(84)

4. Finally, perform the remaining multiplication and subtraction: 20 - 168 = -148

So, the value of the expression 2x - 2(8*x + 4) when x equals 10 is -148.
