Answer:
17k - 25
Step-by-step explanation:
- 5(1 - 5k) - 4(2k + 5) ← distribute parenthesis
= - 5 + 25k - 8k - 20 ← collect like terms
= 17k - 25
Step-by-step explanation:
distribute -5 and -4
-5×1, -5×-5k and -4×2k, -4×5
so,
negative times negative is positive and positive times negative is negative
-5+25k-8k-20
add common variables
-5-20+25k-8k
-25+17k
