Answer:
4-x^2/x^2
Step-by-step explanation:
x+1/x -1 - x - 1/x + 1 + 4/x^2 - 1
1/x - 1 - 1/x + 1 + 4/x^2 - 1
-1 + 1 + 4/x^2 - 1
4/x^2 - 1
4 - x^2/x^2
Okay so a 24hr clock is very simple. We usually turn to "PM" when its 12:00 (day time).
In the 24hr clock we do not, we don't use PM or AM but its crucial to know when converting a standard clock time to military time (aka. 24hr).
9:30 PM in 24hr clock is 12:00 + 9:30 because 9:30 is past that first 12 hours.
So in 24hr clock time it is 21:30. You can also count backwards from midnight to figure it out, for example 12:00 AM (midnight), minus 9:30 is 2:30. Therefore 24:00-2:30=21:30.
Hopefully it helps, heart will help me alot too!
Answer:
10.4 inches
Step-by-step explanation:
The side lengths of a square are all equal. The formula to find the area of a square given a side length s is s².
s² = 109
Taking the square root gives us approximately 10.4 inches.
5.5 or either they would all get 4
bear in mind that, though the square has two valid roots, one negative and one positive, the hypotenuse is just a radius distance, and therefore is never negative.
