Пошаговое объяснение:

-0,5(24х +8)= - 12х -4, при х=2

-12•2-4=-24-4= - 28.

Answer 3

To calculate the expression $-0.5(24x + 8)$ when $x = 2$, you substitute $x = 2$ into the expression and perform the calculation:

$$-0.5(24 \times 2 + 8)$$

Now, let's solve this step by step:

1. $24 \times 2 = 48$
2. $48 + 8 = 56$
3. $-0.5 \times 56 = -28$

So, $-0.5(24x + 8)$ when $x = 2$ is $-28$.
