Answer:
Length = 16 inches and width = 12inches
Step-by-step explanation:
A = 192 in² . The width is 4 + 1/2x.  therefore let x = length
Area = LW
192 =  x(4 + 1/2 x)
192 = 4x + 1/2x²       
 384 = 8x  + x²                            Multiply each term by 2 to make a  
384 + 16 =  x² + 8x + 16              Complete the square
400 = (x  + 4)²         

± 20 = x + 4
 20 = x + 4  or  -20 = x + 4
20 - 4 = x     or  -20 - 4 = x
     16 = x   or   -24 = x   reject the negative amount
    Length = 16
    width = 4 + 1/2(16);   4 + 8 = 12

Ok the w to your question is to cross multiply <span>216=9m
m=24
</span>
        
                    
             
        
        
        
For the first draw, the probability of an ace is ( 4 / 52 ).
Now there are only 51 cards left in the deck.
For the second draw, the probability of a king is  ( 4 / 51 ).
The probability of both events is
(4/52) (4/41) = (16/2,652)
Divide top and bottom by 4:
(16/2,652) = <em>4/663</em> .  That's <em>choice-C </em>.
