48 cubic feet of mulch
Step-by-step explanation:
12 feet long x 4 feet wide x 1 foot deep of mulch= 48 cubic feet of mulch
I’m pretty sure the 2nd one is the associate property and the 3rd one is the additive inverse property
Hope this helps :)
Answer:
80.4
Step-by-step explanation:
21.03 + 80.4 - 21.03
21.03 - 21.03 cancel each other out because it equals 0.
The equation becomes 0 + 80.4 = 80.4
The total area of pool and border = 361 square feet.
Length of square pool = x
Length of square pool plus border = (x + 1 +1 ) = x + 2
There is 1 foot length on each side on the x length.
The other length of the square pool and border = (x + 2)
Area = (x+2)(x+2)
(x + 2)(x +2) = 361. Let A = x +2
A*A = 361
A² = 361 Take square root of both sides
A = √361
A = 19
A = x + 2 = 19
x = 19 - 2
x = 17
Area of square pool = x*x = 17*17 = 289
Area of the pool = 289 square feet.
