I am not understanding the question would you like a fraction????
        
             
        
        
        
Answer:
to find the scale factor we just need to take one of the side lengths of the larger figure, 20, and divide it by the corresponding side length in the smaller figure, 8. Therefore 20/8 is correct
Step-by-step explanation:
 
        
             
        
        
        
35 = 7 * 5 
(7n + 3)(5n + 1) 
= 35n^2 + 7n + 15n + 3
= 35n^2 + 22n + 3
so answer is
(7n + 3)(5n + 1) 
        
             
        
        
        
Answer:
The rate of change of temperature is 1.29 degree Celsius per second.   
Step-by-step explanation:
We are given the following information in the question:
The temperature at a point (x, y) is T(x, y), measured in degrees Celsius where x and y are measured in centimeters.


We have to find the rate at which the temperature is rising on the bug's path after 14 seconds.
At t = 14 seconds, we have,

To find rate of change of temperature, we differentiate,

Thus, the rate of change of temperature is 1.29 degree Celsius per second.
