1. A swimming pool has the dimensions shown below. A path three feet wide surrounds the pool.
113 feet
(7x-2) feet
1 Write an expression that represents the perimeter of the path.
2 Justice swims four laps the length of the pool, then swims 3 laps the width of the pool
with his little sister, Keraline. Write an expression for the length of the laps he swam.
3
\f x=12, what is the perimeter of the pool?
4 Write an equivalent expression for (Ba?-150+92-60-99-20).

Step-by-step explanation:

Pool is 113 ft long and (7x-2) ft wide.

Pool + path is 113+2×3 = 119 ft long and 7x-2+2×3 = 7x+4 ft wide

Perimeter of pool + path = 2(119) + 2(7x+4) = 14x + 246 feet

I'm assuming that a lap is one full circuit.

4 lengthwise laps = 4×2×119 = 952 ft

3 widthwise laps = 3×2(7x-2) = 42x-12 ft

total = 42x + 940 ft

step-by-step explanation:

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
