Пошаговое объяснение:

k+1-10+5k-5k-k-5=k+1-10-k-5=1-10-5=-4

Answer 3

Let's simplify the given expression step by step:

K + 1 - 5(2 - k) - k(5 + 1) - 5

First, distribute the multiplication:

K + 1 - 10 + 5k - 5k - k - 5

Now, combine like terms:

(1 - 10 - 5) + (k - 5k - k) + (-5)

-14 + (-5k) + (-5)

Finally, combine all the terms:

-14 - 5k - 5

This simplifies to:

-19 - 5k
