Answer:
The slope of the given points is  
Step-by-step explanation:
If two given points on any line equation  are A(a,b) and B(c,d).
The the slope of AB is given as  
Noe, here the points are given as (c,4) and (2,6)
So, the slope 
Hence, the slope of the given points is  
 
        
             
        
        
        
Answer:
132 feet
Step-by-step explanation:
we know that
The scale is equal to 
That means ---> 1 inch in the model represent 12 feet in the actual
To find the actual dimensions of the airplane, divide the dimensions of the model by the scale
so

 
        
             
        
        
        
Answer:
OB=4
Step-by-step explanation:
Step 1: Subtract 5 from both sides.
4x+5−5=21−5
4x=16
Step 2: Divide both sides by 4.
4x/4=16/4
x=4
Answer:
x=4

Answer:
60
Step-by-step explanation:
Area of trapezoid:

The top base of the trapezoid is given as 7 cm. The bottom base of the trapezoid can be found with 7+5+5 = 17 cm. The height is given as 5 cm. Then, plug these values into the formula.

= 
= 
= 60
