The square root of 144x^2 = 12 x
and square root of + 81 = 9 or -9
if this polynomial were a perfect square then its factors would be
(12x - 9)(12x - 9)
but its not a perfect squre because (12x - 9)(12x - 9) = 144x^2 - 216x + 81.
If 11.25 inches snow fell in 4.5hrs,
Then for each hr how much snow fell?
So,
4.5 : 11.25
To find how many inches that fell per hour who would need to divide the number of inches by the numbers of hours
11.25 divided by 4.5 = 2.5
So the answer would be 2.5 inch was of snow per hour
I'm not exactly sure of what you mean, but if the number (for example) were 2,3, and 6 you could say 2 and 6 multiply to get 6 and 6 divided by 2 would be 3 and so on. You could do this with any operation. Hope this helps, and sorry if this wasa little unclear.
Answer: 0.7 is the rate change between the two points
Answer:
$25.00
Step-by-step explanation:
You already know that $85 is an additional fee added to the monthly fees.
So, you first have to subtract 85 from $685 to get the total amount of monthly fees paid over 2 years.
685-85= 600
So, you can conclude that $600 is the total amount of monthly fees paid.
Now, you want to divide 600 by (the number of months in 2 years) to get the amount of monthly fees.
Since there is 24 months in 2 years you do:
600/ 24 which equals 25.
In conclusion, you can find that the monthly fee is $25.00.
