Answer: The answer is A : 6x^2+24x+24
Step-by-step explanation:
(2x+4)(3x+6)
multiple the two equations together
2x*3x=6x^2
2x*6=12x
4*3x=12x
4*6=24
combine like terms 
6x^2+12x+12x+24
6x^2+24x+24

Step-by-step explanation:
we have

using a graphing tool 
see the attached figure N
The range is the interval--------> (-∞,8]

case A) 
using a graphing tool
The range is the interval--------> [-8,∞)

case B) 
using a graphing tool
The range is the interval--------> [8,∞)

case C) 
using a graphing tool
The range is the interval--------> (-∞,8]

case D) 
using a graphing tool
The range is the interval--------> (-∞,-8]

 
        
             
        
        
        
The answer is 91 because the tens place has to be 8 more so in the 80's, 8 would be 8 more than 0 and 0 is not one of the digits and it's a 2 digit number so it can't go to the 100's so 91 is the best answer. I hope this helped you
