Answer: B
<u>Step-by-step explanation:</u>
   x³ - 3x²  + 16x - 48 = 0
→ x²(x - 3)   + 16(x - 3) = 0
→ (x² + 16) (x - 3) = 0
→ (x² - (-16)) (x - 3) = 0
→ (x - 4i)(x + 4i)(x - 3) = 0
→ x - 4i = 0    x + 4i = 0   x - 3 = 0
→  x = 4i          x = -4i        x = 3

Answer:
23
Step-by-step explanation:
if y=8 then you plug it inti the equation
2(8)+7
16+7=23
 
        
                    
             
        
        
        
6*2=12
32-12=20
20/2=10. 
Perimeter is all the way around an object. So take 6 two times and minus that from 32. Answer of that divide by 2 to get the length. Length of one side is 10 ft.
