To find the area of a square you multiply Length by the Height. Since squares have equal length sides the number has to be the same for the length and the height.

$\sqrt{169} = 13$

Find the midpoint between 1 + 9i and 5 — 3i

stellarik [79]

Answer:

3+3i

Step-by-step explanation:

The mid point formula in a complex plane is for points a+bi and s+ti is

$Midpoint = \frac{a+s}{2} +\frac{(b+t)i}{2} \\$

For points 1 + 9i and 5 — 3i

$Midpoint = \frac{1+5}{2} + \frac{(9-3)i}{2}$

$Midpoint = \frac{6}{2} + \frac{6i}{2}$

Midpoint = 3 + 3i
