Answer:
The answer is -12
Step-by-step explanation:
2xy + 3x + 4x + 3 if x = 5 and y = -5
Now,
2xy + 3x + 4x + 3
2(5)(-5) + 3(5) + 4(5) + 3
-50 + 15 + 20 + 3
38 - 50 = -12
Thus, The answer is -12

Answer: hmmmmmmmm sol and hmmmmmmm lemme think and charger?
Step-by-step explanation:
Solution:
Given: zj = 3- j2, zz = - 4 + j3
Part a:
zj = 3- j2 = 
zz = - 4 + j3 = 
Part b:
|zj| = |3− j2| = √3² +(−2)² = √13 = 3.60
|z1| = √(3− j2)(3+ j2) = √
13 = 3.60.
Part c:
With the help of part a:
z1z2 =
