Answer:
8a^3.
Step-by-step explanation:
(a+b)^3=a^3+b^3+3a^2b+3ab^2
(a-b)^3=a^3-b^3-3a^2b+3ab^2
(a+b)^3+(a-b)^3=2a^3+6ab^2
According to the question
(a+b)^3+(a-b)^3+6a(a^2-b^2)
Put in the value
=2a^3+6ab^2 +6a^3–6ab^2
=8a^3
I’m pretty sure the average rate of change is 1
Answer:
25
Step-by-step explanation:
a1 = - 3 Given
d = 2 Given
n = 15 Given
Formula
tn = a1 + (n - 1) * d
Substitute and solve
t15 = -3 + (15 - 1) * 2 Calculate what's in the brackets.
t15 = -3 + 14*2 Combne
t15 = -3 + 28 Add the two terms
t15 = 25
