Evaluate the expression when a=−2, b=3, and c=−8. −ab3−ac=?

= 2

Step-by-step explanation:

Input the numbers

-(-2) * 3 * 3 - (-2) * (-8) = ? Note - * - as in -(-2) = + 2

2 * 9 + 2 * -8 = ?

18 - 16 = 2

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 is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
