Question

(b−c−4,8)−(−c−b−4,8) Ответ:?

Answer 1

Правильный ответ это: 2b

Answer 2

To calculate the expression, let's break it down step by step:

1. (b - c - 4, 8): This represents a point in 2D space with coordinates (b - c - 4, 8).

2. (-(c + b) - 4, 8): This represents another point in 2D space with coordinates (-(c + b) - 4, 8). The negative sign is applied to both c and b, and then the result is subtracted from 4.

Now, let's simplify the expression:

1. (b - c - 4, 8)
2. (-(c + b) - 4, 8)

Now, when we subtract the second point from the first point, we perform coordinate-wise subtraction:

(b - c - 4, 8) - (-(c + b) - 4, 8) = (b - c - 4 - (-(c + b) - 4), 8 - 8)

Let's simplify further:

(b - c - 4 + c + b + 4, 0)

Now, the (-c) and (+c) cancel out, and the (-4) and (+4) also cancel out:

(2b, 0)

So, the final answer is (2b, 0).
