Arectangle has a perimeter of 8x+6 and a length of 3x. what is the width

let A and B be the two sides of the rectangle.

The perimeter is the sum of its four sides:

perimeter = A + B + A + B = 2A + 2B = 8x + 6

We are also given one of its sides (length), say, A = 3x

and so we know how to get the second side (width) B:

2A + 2B = 8x + 6

6x + 2B = 8x + 6

2B = 2x + 6

B = x + 3

The width of the rectangle is x + 3

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
