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.
X < -40.5
To find this, here are the steps:
Combine like terms like so:
-4x - 49 > 113
Then, begin to isolate the variable x by adding 49 to both sides leaving you with:
-4x > 162
Then divide by negative four. Don’t forget, dividing by negatives switches the way the sign points so your final product will be:
x < -40.5

Answer:
4th option: 38t = 532
Step-by-step explanation:
t = 38
?t = 532
14t =532
I don't really know how to explain this but basically, we know 1t is 38, so we know 38 x t will give use 532. This is why I chose the last equation of:
38t = 532
The answer would be 14 trips just for extra information.
Answer:
12p - 13q + 20rs
Step-by-step explanation:
Subtract 8p + 9q -5rs from – 4p - 4 q +15 sr
– 4p - 4q + 15sr - (8p + 9q -5rs)
= -4p - 4q + 15sr - 8p - 9q + 5rs
= -4p - 8p - 4q - 9q + 15rs + 5rs
= -12p - 13q + 20rs
– 4p - 4q + 15sr - (8p + 9q -5rs) = 12p - 13q + 20rs
