Answer:
2.5+7.5+-10n+-20
Step-by-step explanation:
Multiply everything on the inside by the number on the outside and put it together with addition signs.
-2.5(-3+4n+8)
-2.5*-3=7.5
-2.5(7.5+4n+8)
-2.5*4= -10
-2.5(7.5+-10n+8)
-2.5*8=-20
-2.5+7.5+-10n+-20
Answer: 7.5 + 200n
Step-by-step explanation:
(-2.5 • -3) + (-2.5 • 4n) + (-2.5 • 8)
7.5 + -10n + -20
7.5 + 200n
