Answer:
17 k + -25
Step-by-step explanation:
Simplify the following:
-5 (1 - 5 k) - 4 (2 k + 5)
-5 (1 - 5 k) = 25 k - 5:
25 k - 5 - 4 (2 k + 5)
-4 (2 k + 5) = -8 k - 20:
25 k + -8 k - 20 - 5
Grouping like terms, 25 k - 8 k - 20 - 5 = (25 k - 8 k) + (-5 - 20):
(25 k - 8 k) + (-5 - 20)
25 k - 8 k = 17 k:
17 k + (-5 - 20)
-5 - 20 = -25:
Answer: 17 k + -25
Answer:
