What is the greatest common factor of 4x^5 y^12 - x^15 y + 8x^10 y^8

GCF:   x^5y

Step-by-step explanation:

4x^5 y^12 = x^5y (4y^11)

x^15 y = x^5y (x^10)

8x^10 y^8 = x^5y (x^5y^7)

So

GCF of 4x^5 y^12 - x^15 y + 8x^10 y^8 = x^5 y

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
