Sagot :

Sure, let's simplify the given expression step-by-step:

Given expression:
[tex]\[ -k + 2(-2k - 5) \][/tex]

1. Start by distributing the coefficient 2 to each term inside the parentheses:
[tex]\[ 2(-2k - 5) = 2 \cdot (-2k) + 2 \cdot (-5) \][/tex]
Simplifying this, we get:
[tex]\[ = -4k - 10 \][/tex]

2. Now substitute this back into the original expression:
[tex]\[ -k + (-4k - 10) \][/tex]
Which simplifies to:
[tex]\[ -k - 4k - 10 \][/tex]

3. Combine the like terms:
[tex]\[ -k - 4k = -5k \][/tex]
So we have:
[tex]\[ -5k - 10 \][/tex]

Therefore, the simplified expression is:
[tex]\[ -5k - 10 \][/tex]

The correct answer is:

(B) [tex]\(-5k - 10\)[/tex]
