Given:
Steven wrote this equation:

To find:
The error in Steven's reasoning and then find the correct product.
Solution:
We have,

This statement is incorrect because we cannot write product directly as Steven wrote. 
We need to multiply the place values of each digit of first number with the place values of second number and then we need to add the resulted values.




Therefore, the correct product is 72.
 
        
             
        
        
        
Answer:
parallel
Step-by-step explanation:
find the slope of each line
Line 1   (5-2)/(-4-2) = 3/-6 =-1/2
Line 2  (-4--9)/(-6-4)= 5/-10 = -1/2
 
        
             
        
        
        
Step-by-step explanation:
Distance = rate × time
If b is the speed of the boat in still water, and c is the speed of the current, then:
60 = (b + c) × 4
35 = (b − c) × 3.5
Simplifying:
15 = b + c
10 = b − c
Add the equations together:
25 = 2b
b = 12.5
Plug into either equation to find c:
c = 2.5
The speed of the boat is 12.5 km/h, and the speed of the current is 2.5 km/h.
 
        
                    
             
        
        
        
The correct answer is 10,000
        
                    
             
        
        
        
Answer:8,400 miles
Step-by-step explanation: You would do 2,100•4 because you are driving 2,100 miles a week and there are 4 weeks you would have to times the amount of miles by how many weeks
