(2+2i)(5+3i)
 10+6i+10i+6i^2
 10+16i+6(-1)
 4+16i
When you have an “i^2”, you also have a negative one. The simplified answer is 4+16i
        
                    
             
        
        
        
Answer:
8y = -6
Step-by-step explanation:
x + 6y -x +2y = 9 +(-15) ➡ 8y = -6
 
        
             
        
        
        
3x-6=6(x+2)  
3x-6=6x+12  3x-6x=6+12  
-3x=18  X= 18/-3  X= -6  first number .
For second number you substitute x+2.
-6+2=-4     
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Let the equation of the perpendicular line is, 
y = mx + b
where m = slope of the line 
b = y-intercept 
From the graph, slope of the line passing through (0, -1) and (3, 1),
m' =  
 
m' = 
m' = 
To get the slope (m) of this line we will use the property of perpendicular lines,
m × m' = (-1)
m ×  = -1
 = -1
m = 
Equation of the perpendicular line will be,

x-intercept of the line is (-3) therefore, point on the line is (-3, 0)
0 = 
b = 
Equation of the line will be,
