There are 6 rectangular flower gardens each measuring 18 feet by 13 feet in a rectangular city park
Georgia [21]

Answer:

Step-by-step explanation:

The formula for determining the area of a rectangle is expressed as

Area = length × width

There are 6 rectangular flower gardens each measuring 18 feet by 13 feet in a rectangular city park. The area of each garden is

Area = 18 × 13 = 234 ft²

Since there are 6 gardens, the total area covered by the 6 gardens is

6 × 234 = 1404 ft²

The rectangular park measures 70 feet by 160 feet. The total area of the park is

Area = 70 × 160 = 11200 ft²

The number of square feet of the park that is not used for flower gardens is

11200 - 1040 = 10160 ft²

The formula for determining the perimeter of a rectangle is

2(length × width)

Total number of feet covered by rectangular city park is

2(70 + 160) = 460 ft

Number of feet covered by the 6 rectangular gardens is

6[2(18 + 13)] = 372 ft

The number of feets not used for flower gardens is

460 - 372 = 88 feet

Put in slope intercept form
LiRa [457]
These require you solve for y. Do that by subtracting the x-term, then dividing by the y-coefficient.

5. 3y = 7x -9
  y = (7/3)x -3

6. 6y = -2x -3
  y = (-2/6)x -3/6
  y = (-1/3)x -1/2

7. 8y = 2x + 12
  y = (1/4)x +3/2
