Answer:
a^3 + a^2
Step-by-step explanation:
Distribute the term left of each set of parentheses, then combine like terms.
-a²(3a - 5) + 4a(a² - a) =
= -3a^3 + 5a^2 + 4a^3 - 4a^2
= a^3 + a^2

Answer:
k = 0.0916
Step-by-step explanation:
T(t) =
from question; t = 12 mins , = 50 C , = 80 C , T = 60 C
60 = 50 + (80 - 50)
60-50 = 30
10/30 = (Taking natural Log of both sides)
In(0.3333) = In
-1.0986 = -12k
k = 0.0916
