Answer:
Step-by-step explanation:
16 = 2 *2 * 2 * 2 = 2⁴
16y⁴ = (2y)⁴
x⁴ - 16y⁴ = x⁴ - (2y)⁴
               = (x²)² - [ (2y)² ]²    
  {Use identity = a² -b² =(a +b)(a- b). Here a =x² & b =(2y)²}
               = (x² + (2y)² ) (x² - (2y)² )  
                = (x² + 4y²) (x² - 4y²)

40 x 5280 = 211200 feet per hour
211200 / 3600 = 58.666 = 59 feet per second
 
        
             
        
        
        
Answer:
ok here ya go
Step-by-step explanation:
A way that I would teach someone something that I learned in math this year to someone else is simple. I would start by writing everything out so that they have a visual of what I am teaching them. I would also use a visual of a real world situation so that it relates to something they would understand. Teaching someone younger than you means they probably will not understand as easy as you understood it so, I would be very slow and make sure if they are confused to help them. I would also make sure not to be too bossy, understanding that they may not understand and that is ok.
