Arectangular swimming pool is represented by x as the width and one less than twice the width as the length. if the area of the swimming pool is given by 28 sq. ft., which equation could be used to model the area of swimming pool?

a) 28 = 2x-1•x

b) 28x = 2x -1

c) 28 = (2x-1) + (x)

d) 28 = (2x - 1) (x)

Option D.

Step-by-step explanation:

Let

x ----> the width of the rectangular swimming pool in feet

y ----> the length of the rectangular swimming pool in feet

we know that

the area of the  rectangular swimming pool is equal to

we have

so

-----> equation A

---> equation B

substitute equation B in equation A

answer: the answer to your question is parallel

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
