PLEASE HELP ASAP Q1: What signals you that factoring by grouping is the best method to use when factoring a
problem? How would you know if it is factorable or prime?

You know a number is not factorable or prime if nothing multiplies to it.

Step-by-step explanation:

For example there are no numbers that multiple to 7, same with 19. No 2 numbers will ever be able to = to 7 or 19 for example.

Hope this helps!!!

prime numbers would be 2,4,6,8,10,12, and etc

Step-by-step explanation:

factorable means say we have the number 32 it factors down to 16 then 16 factors down into 8 then 8 goes down into 4 then 4 goes dow into 2

hope this helps

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
