svet-max [94.6K]

Answer:

$=27a^3b^3+54a^2b^2c+36abc^2+8c^3$

Step-by-step explanation:

$(3ab+2c)^3$

$=(3ab+2c)$ × $(3ab+2c)$ ×

$=(3ab+2c)(9a^2b^2+12abc+4c^2)$

$=(3ab)(9a^2b^2)+(3ab)(12abc)+(3ab)(4c^2)+(2c)(9a^2b^2)+(2c)(12abc)+(2c)(4c^2)$

$=27a^3b^3+36a^2b^2c+12abc^2+18a^2b^2c+24abc^2+8c^3$

$=27a^3b^3+54a^2b^2c+36abc^2+8c^3$

The Newport Crab Company marks the location of its crab pots with colored balloons. They mark every fourth pot with a red balloo

sasho [114]

Answer: There are 310 pots that have three different colored balloons attached.

Step-by-step explanation:

Since we have given that

Number of crab pots in the bay = 600

Part of red balloon = $\dfrac{1}{4}$

Part of blue balloon = $\dfrac{1}{6}$

Part of yellow balloon = $\dfrac{1}{10}$

So, Number of pots that have different colored balloons attached is given by

$\dfrac{1}{4}\times 600+\dfrac{1}{6}\times 600+\dfrac{1}{10}\times 600\\\\=150+100+60\\\\=310$

Hence, there are 310 pots that have three different colored balloons attached.
