Find the zeros of y= x - 4x - 9 by completing the square.
O A. *= 2: 113
O B. x= 3+ /13
O c. *= +3
O D. x=-21,13

The zeros for the given equation are A.

Step-by-step explanation:

Step 1:

To solve for x in a polynomial equation, we use the formula

Here a is the coefficient of , b is the coefficient of and c is the coefficient of the constant term.

In the given equation, .

Step 2:

Substituting the values of a, b, and c in the equation, we get

So the answer is option A.

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
