This is a quadratic formula with a general form of a²x + bx + c = 0. For quadratic equations, we can solve for its two roots using the quadratic formula shown in the attached picture.
a = -3
b = -4
c = -4
x = [-(-4) + √(-4)² - 4(-3)(-4)]/2(-3) = 
<em>2 + √-32/2</em>x = [-(-4) - √(-4)² - 4(-3)(-4)]/2(-3) =
<em> 2 - √-32/2</em>
 
        
        
        
Answer:
The median is 2
Step-by-step explanation:
Here, we want to get the median for the number of pencils 
Firstly, we have to write out the numbers that form the box plot ; we have this as;
1,1,1,2,2,2,2,3,3,5 
the median is sum of the 5th and 6th term divided by 2
The 5th term is 2
The 6th term is 2
So the median is;
(2 + 2)/2
= 4/2 = 2 
 
        
             
        
        
        
The total time taken to cover 12 miles distance is 5 hours. 
<u>Given the Parameters</u> : 
- Total distance hiked = 12 miles 
Recall : 
Let :
<u>We could create an equation thus</u> : 
Total distance = 3(2) + 2(t - 2)
12 = 6 + 2t - 4 
12 = 2 + 2t 
12 - 2 = 2t 
10 = 2t 
t = 10/2 
t = 5 
Therefore, the total time taken is 5 hours
