−5(1−5k)−4(2k+5) pleas
Kazeer [188]

Answer:

<h2>33k - 25</h2>

Step-by-step explanation:

-5(1 - 5k) - 4(2k + 5)      <em>use distributive property a(b + c) = ab + ac</em>

= (-5)(1) + (-5)(-5k) + (-4)(2k) + (-4)(5)

= -5 + 25k - 8k - 20           <em>combine like terms</em>

= (25k - 8k) + (-5 - 20)

= 33k - 25
