Answer:
A =16
Step-by-step explanation:
Since its a Parallelogram and in a parallelogram the opposite side are always equal. AB and CD are opposite sides of a parallelogram. Hence CD =16
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:
it is 5.8
