Find the area and perimeter of the following rectangle. the lengths are 4x+y+2; and 3x+3y. the widths are 2x+y+1 and 12

Equating the lengths, we have:

Equating the widths, we have:

Solving the two equations simultaneously gives that x = 4 and y = 3.

Thus, the length is 4(4) + 3 + 2 = 21 and the width is 12.

Therefore area = length times width = 21 x 12 = 252 square units

perimeter = 2(length + width) = 2(21 + 12) = 2(33) = 66.

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
