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
You would is this case use the perfect square rule. So your would squareroot 9r^2 and 25 to get 3r+5 then you would square this equation to get (3r+5)^2

Answer:
-6/7.
Step-by-step explanation:
-1/2 w -3/5 = 1/5w
-1/2 w - 1/5 w = 3/5
Multiply through by 10:
-5w - 2w = 6
-7w = 6
w = -6/7.
Answer:
1/2n - 11 = -25
Hope this helps you! Have a good night!
Also, n = -28
1/2n - 11 = -25
1/2n - 11 + 11 = -25 + 11
1/2n = -14
1/2n / 1/2 = -14 / 1/2
n = -28
Check:
1/2(-28) - 11 = -25
-14 - 11 = -25
-25 = -25
