The quadrants and the given numbers are shown in the figure below.
Answer:
The order of the complex numbers, numbered from the first quadrant are
4 + i
-2 + 2i
-1 - 3i
3 - 4i
I think 20.10 of 67 is 13.467.
Answer:

--- True
Step-by-step explanation:
Given



Solving (a): 
From the given parameters, we have:


So:

Collect like terms

Solving (b) m(x) = f(x) = g(x)?
In (a), we have:

And
--- given
By comparison:

Let's say the sides are "a" first one, "b" second one and "c" the third one
ok, let's say the shortest is "a"
and let's say "b" is -> "<span> twice the length of the shortest side"
so b = 2a
and let's say "c" is -> "</span><span>3rd side 14 more feet than length of shortest side"
so c = a + 14
we know the perimeter ( sum of all sides ) is 154

solve for "a"</span>
