Answer:
(a + b + 2c)(a² + 2ab + b² - 2ac - 2bc + 4c²)
Step-by-step explanation:
Given
(a + b)³ + 8c³ ← this is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²)
Thus
(a + b)³ + 8c³
= (a + b)³ + (2c)³
= (a + b + 2c)( (a + b)² - 2c(a + b) + (2c)² )
= (a + b + 2c)(a² + 2ab + b² - 2ac - 2bc + 4c²)

I hope this helps!
So what I think is that you multiply 4 by 4 or add 4 four times.Then, you would multiply 16 with 12 because there are 12 boxes and each box is 16. After doing that, you will get 192. Hope it helps :)

Answer:
n = 24
q = 8
Step-by-step explanation:
Let:
n = nickels
q = quarters
5n + 25q = 320
n + q = 32
n = 32 - q
Substitute (to solve for q):
5(32 - q) + 25q = 320
160 - 5q + 25q = 320
160 + 20q = 320
20q = 320 - 160
20q = 160
q = 160 ÷ 20
q = 8
Substitute (to solve for n):
n = 32 - q
n = 32 - (8)
n = 24
