Write the expression as a product of polynomials: a(p–q)+q–p

if p and q are symmetric matrices and PQ=QP then which of the following is/are true (A) QP^-1=P^-1Q (B) PQ is a skew symmetric (C) P^-1Q is symmetric (D) and both (A) an (C)

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

the answer will be b x² +x-1
