Let's call the width: w
the lenght is then 3w+4 ("4 more than 3 times the width")
and the parameter would be 2(w+3w+4), that is 2*(4w+4), that is 8w+8. 
this is also equal to 18.4:
8w+8=18.4
8w=10.4
w=1.3
this is the width, and the lenght is: 
4+3*1,3=4+3.9=7.9
and the area is their product:
1.3*7.9=10.27
        
             
        
        
        
Answer: x = 15
Step-by-step explanation:
 
Vertical angles are equal so we can set 47 = 3x + 2
Now just solve the equation for x
47 = 3x + 2
Subtract 2 from each side 
45 = 3x
Divide both sides by 3
15 = x
 
        
                    
             
        
        
        
Answer: 
The probability that he or she is a male or a civilian employee is 1.037068
Step-by-step explanation:
Probability of sworn officers = 0.696
Probability of civilians = 1 - 0.696 = 0.304
Probability of male sworn officers = 0.882*0.696 = 0.6139
Probability of male civilian = (0.304*(1-0.608)) = 0.1192
Hence probability that he or she is a male or civilian employee is
0.6139 + 0.1192 + 0.304 = 1.037068
 
        
                    
             
        
        
        
The maximum height reached is 2.87 meters
<h3>What is maximum height?</h3>
The maximum height of an object is the highest vertical position along the trajectory of the object.
The given parameters are:
 --- the initial velocity --- the initial velocity
 --- the final velocity --- the final velocity
 --- the acceleration --- the acceleration
To calculate the height (s) of the ball, we make use of the following equation of motion:

Substitute known values


Collect like terms

Substitute 9.8 for g


Divide both sides by 19.6

Hence, the maximum height reached is 2.87 meters

Answer:
y = 4x - 7
Step-by-step explanation:
Given the following data;
Points (x, y) = (4, 9)
Slope, m = 4
To write the equation in point-slope form; 
The equation of straight line is y = mx + c
Where;
m is the slope. 
x and y are the points
c is the intercept.
First of all, we would find the intercept c;
9 = 4*4 + c
9 = 16 + c
c = 9 - 16
c = -7
Next, we write the equation in point-slope form;
m = 4 and c = -7
y = 4x - 7
