Answer:
-1 and -5
Step-by-step explanation:
You must account for negative u values (which the abs nullifies).
So 
and 
is what we have to solve for.
As for usual equations, isolate the u variable.
5u + 15 = 10
5u + 15 (-15) = 10 (-15)
5u = -5
u = -1
Now you can do the same operation for the other equation and you should get u = -5.
Let's make sure we did it right by replacing u with one of our solutions (-1 or -5).
That's true. What about the other one?

Answer:
0.34
Step-by-step explanation:
iff we think of them all as a percentage then it looks like
25% + 17% + 21% + 3%
then you add them to get 66%
now you know you are missing 34% to make up the rest of the area.
Answer: Cells typically communicate using chemical signals. These chemical signals, which are proteins or other molecules produced by a sending cell, are often secreted from the cell and released into the extracellular space. There, they can float – like messages in a bottle – over to neighboring cells.
