Answer:
(4 x + 9) (16 x^2 - 36 x + 81)
Step-by-step explanation:
Factor the following:
64 x^3 + 729
64 x^3 + 729 = (4 x)^3 + 9^3:
(4 x)^3 + 9^3
Factor the sum of two cubes. (4 x)^3 + 9^3 = (4 x + 9) ((4 x)^2 - (4 x) 9 + 9^2):
(4 x + 9) ((4 x)^2 - 4 9 x + 9^2)
4×9 = 36:
(4 x + 9) ((4 x)^2 - 36 x + 9^2)
Multiply each exponent in 4 x by 2:
(4 x + 9) (4^2 x^2 - 36 x + 9^2)
4^2 = 16:
(4 x + 9) (16 x^2 - 36 x + 9^2)
9^2 = 81:
Answer: (4 x + 9) (16 x^2 - 36 x + 81)
Answer:
3 packages of plates, 2 packages of cups
Step-by-step explanation:
Find the multiples of 8 and 12, the lowest one they have in common will help with your answer.
8 : 8 16 24 32 40 48 56
12 : 12 24 36 48
The number that they both have (least) in common is 24.
For 8, it is the 3rd multiple and for 12 it would be the second
Answer:
14 and 10
Step-by-step explanation:
14+10=24
14-10=4
Answer:
