Let f(x) and g(x) be polynomials as shown below.

which of the following is true about f(x) and g(x)?
a.
f(x) and g(x) are closed under addition because when added, the result will not be a polynomial.
b.
f(x) and g(x) are not closed under addition because when added, the result will not be a polynomial.
c.
f(x) and g(x) are not closed under addition because when added, the result will be a polynomial.
d.
f(x) and g(x) are closed under addition because when added, the result will be a polynomia

answer: okw

step-by-step explanation:

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

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
