AD is perpendicular to BC so slope Ad = -1/slope of BC
Slope of BC = (2 - (-1)) / (- 6- 3) = 3 / -9 = -1/3
So slope of AD = -1 / (-1/3) = -3/-1 = 3 Answer

Write a number as prime factors means to write the number as a product of numbers, all of which are prime. We start by checking whether the number is divisible by prime numbers, starting from the smallest prime number,2. 
let's divide 24 into its factors. 
first, it's even, so it must divide by 2
24=2*12
12 is also even, so it must divide by 2: 
24=2*12=2*2*6
6 is also even, so it must divide by 2: 
24=2*12=2*2*6=2*2*2*3
3 is not even, but it's a prime number. 
so the solution is
2*2*2*3 
        
                    
             
        
        
        
Answer: 4(5+2) or 4(2+5)
Step-by-step explanation:
8 = 2*2*2
20 = 2*2*5
4(5+2) = 20+8
 
        
             
        
        
        
Answer:
This is because the number '20' is not a perfect square.
Step-by-step explanation:
If you find  , you will be getting 4.4721935955... which is not a whole number, thus 20 is not a perfect square.
