That's false. Take the numbers 1, 3, and 5.
Let a = 1, b = 3, and c = 5.
ab + bc = ac
3 + 15 = 5
18 ≠ 5
Since 18 does not equal 5, this is false. If you were to use the distributive property on ab + bc = ac, you would get
b(a+c) = ac, which doesn't even make sense.
Have a nice day! :)
        
             
        
        
        
Perimeter (P) = 2L + x
             4900 = 2L + x   ⇒  4900 - x = 2L  ⇒  = L
 = L
Area (A) = L · x
A  = ( ) (x)

To solve this, you need to plug in the numbers for <em>h</em>. 
-4(-12) ≥ 8       48 ≥ 8  yes
-4(-7) ≥ 8         28 ≥ 8  yes
-4(-5) ≥ 8        20 ≥ 8  yes
-4(-3) ≥ 8        12 ≥ 8  yes
-4(-2) ≥ 8         8 ≥ 8  yes
-4(-1) ≥ 8         4 ≥ 8  no
-4(1) ≥ 8          -4 ≥ 8  no
-4(3) ≥ 8         -12 ≥ 8 no
-4(8) ≥ 8         -32 ≥ 8  no
Hope this helped!
 
        
             
        
        
        
Answer:
 = - 3
 = - 3
Step-by-step explanation:
There is a common ratio between consecutive terms of the sequence, that is
r = 9 ÷ - 3 = - 27 ÷ 9 = 81 ÷ - 27 = - 243 ÷ 81 = - 3
The recursive formula is of the form
 = r
 = r = - 3
 = - 3
