Not sure, but the areas of a triangle is BH/2 so the dimensions should be 8 and 6 then 10. 
8 x 6 = 48 
48/2 = 24
Maybe that can help with the equation
        
                    
             
        
        
        
Answer:
B
Step-by-step explanation:
y= -x+18 and y= 3/4x+4
use slope intercept form: y=mx+b
m = slope
b = y-intercept
 
        
             
        
        
        
Answer:
1/3
Use the slope formula and simply the fraction.
 
        
             
        
        
        
Answer:
The simplified form of given expression is 3/5.
Step-by-step explanation:
The given expression is

We need to find the product of two factions using diagram.
For 3/4, draw a box and divide it in 4 equal parts by using vertical lines. The  color three parts of it.
For 4/5, draw a box and divide it in 5 equal parts by using horizontal lines. Then color the four parts of it.
Now combined both boxes and shown below.
From the below figure it is clear that 
The number of common shaded small boxes =  12
Total number of small boxes = 20
The required fraction is


Cancel out common factor.

Therefore, the simplified form of given expression is 3/5.
