Answer:
-2, 3,  -0.5 + 0.866i,   -0.5 - 0.866i.
Step-by-step explanation:
As the last term is -6 , +/- 2 , +/- 3 are possible zeroes. 
Try 2:-
(2)^4 - 6(2)^2 - 7(2) - 6 = -28 so  2 is not a zero.
3:-
(3)^4 - 6(3)^2 - 7(3) - 6 = 0 so 3 is a zero.
(-2)^4 - 6(-2)^2 - 7(-2) - 6 =  0 so -2 is also a zero.
Divide the function by (x +2)(x - 3),  that is  x^2 - x - 6
gives  x^2 + x + 1
x^2 + x + 1
So we have x^2 + x + 1 = 0
x =  [-1 +/- √(1^1 - 4*1*1)] / 2
= -1 + √(-3) / 2 , - 1 - √(-3)  / 2.
= -0.5 + 0.866i, -0.5 - 0.866i
 
        
             
        
        
        
Answer: $180
4ft + 5ft + 4ft + 5ft = 18ft
18 x 10 = 180
        
                    
             
        
        
        
That literally means the numbers '5' and '12' written like this: 5 + 12
represent the sum of 5 and 12, which is the same as 5 + 12 (because the sum is when all the numbers are added up).
So it's saying 5 + 12 equals to 17.
