Hi
k (a+b) = ka+kb 
so :  8 (3x+4) =   8*3x +8*4  =  24x +32 
 
        
                    
             
        
        
        
Answer: 30° and 330°
<u>Step-by-step explanation:</u>
sec θ = 
sec θ = 
 =
 = 
cos θ = 
cos θ = 
cos θ = 
cos θ = 
Look at the Unit Circle to see that cos =  at 30° and 330°  ( which is equivalent to π/6 and 11π/6)
 at 30° and 330°  ( which is equivalent to π/6 and 11π/6)
 
        
                    
             
        
        
        
Answer:
8
Step-by-step explanation:
Sum the parts of the ratio 4 + 2 = 6 parts
Divide 24 by 6 to find the value of one part of the ratio
24 ÷ 6 = 4 ← value of 1 part, thus
number of boys = 4 × 4 = 16
number of girls = 2 × 4 = 8
Hence there are 8 more boys than girls
 
        
             
        
        
        
Answer:
d = 7, 3
Step-by-step explanation:
First, you need to isolate the absolute value
-3|d - 5| = -6
divide both sides by -3:
|d - 5| = 2
break into 2 equations:
d - 5 = 2, d - 5 = -2
solve both equations and collect solutions:
d = 5 + 2, d = 5 - 2
d = 7, 3
