Answer:

First choice: m = -4

Step-by-step explanation:

The second equation is already solved for n, so lets's use the substitution method and substitute m - 2 for n in the first equation.

m - 2n = 8

m - 2(m - 2) = 8

m - 2m + 4 = 8

-m + 4 = 8

-m = 4

m = -4

The point A,B,C and D represent the complex number Z1,Z2,Z3 and Z4 and O is the origin. If OABC is a parallelogram, and Z1=1+3i

aleksley [76]

Complex numbers are divided into two parts; real and imaginary parts. The value of Z3 is $5+ 8i$

Given that:

$Z_1 = 1 + 3i$

$Z_2 = 4 + 5i$

Since O is the origin, then:

$C = OA + OB$

This means that:

$Z_3 = Z_1 + Z_2$

So, we have:

$Z_3 = 1 + 3i + 4 + 5i$

Collect like terms

$Z_3 = 1 + 4+ 3i + 5i$

$Z_3 = 5+ 8i$

Hence, complex number Z3 is $5+ 8i$
