Answer 1

Ответ:

Пошаговое объяснение:

-8(2×(-8)-4)-6×(-8)(3×(-8)-2)=

-8×(-20)-48×(-26)=1408

Answer 2

To evaluate the expression X(2x-4) - 6x(3x-2) when x = -8, follow these steps:

Step 1: Replace all occurrences of 'x' with '-8' in the expression. Step 2: Perform the necessary calculations.

Let's start:

X(2x-4) - 6x(3x-2)

When x = -8:

X(2(-8) - 4) - 6(-8)(3(-8) - 2)

Now, calculate the values inside the parentheses:

X(-16 - 4) - 6(-8)(-26)

Next, perform the multiplication and addition/subtraction:

X(-20) - 6(208)

Now, substitute 'X' with '-8':

-8(-20) - 6(208)

Finally, calculate the final result:

160 - 1248 = -1088

So, the expression X(2x-4) - 6x(3x-2) evaluates to -1088 when x = -8.
