Well it goes in an odd patter like 5,3,1,3,5 so the first one would be -2
Answer:
I believe it's the first one
The fourth option because ab = 10 and bc = 10 and ac = 2sqrt(10)
20+ 2Sqrt(10)
answer is the fourth option
Answer:
-89/56
or simplified that would be
-1 and 33/56
Step-by-step explanation:
U-value is generally used to rate door or window units. The lower the U-Value, the more energy efficient the system in question will be. A U-value is typically a low number because it is a rating of how much heat energy is lost or gained. If we look at the two values mathematically, U-value is the reciprocal of R-value; that is, U = 1/R and R = 1/U.
