Answer:
The number of pools clean per hour is 1.5
Step-by-step explanation:
Given as :
The number of pools clean in 8 hours = 12
The number of pools clean in 7.5 hours = 9
Let The number of pools they clean per hours = x
I.e x = 
+ 
Or, x = 
Or, x = 
∴ x = 
I.e x = 1.5
Hence The number of pools clean per hour is 1.5 Answer
Answer:
<h2>
x=-1 and x=2</h2>
Step-by-step explanation:
The "holes" are the x-es where function doesn't exist.
one must not divide by 0, so given function doesn't exis if the denominator is equal 0
The product {(x+1)×(x-2)} is equal 0 if any of factors {(x+1),(x-2)} is 0, so
x + 1 = 0 or x - 2 = 0
x = - 1 or x = 2
Answer is A, all interior angles and exterior sun must be 360. those are interior angles so they have to add up to 180
