6 multiplied by 4 is 24 feet.  Then convert it to meters by multiplying .3048 by 24 which means the answer is 7.3152 meters
        
             
        
        
        
Kevin painted  of the wall.
 of the wall.
Solution:
Fraction of the wall painted by Elena = 
Fraction of the wall painted by Matthew = 
Fraction of the wall painted by Kevin = ?
Full wall can be taken as 1.
<u>To find the wall painted by Kevin:</u>
Rest of the wall = Full wall – painted by Elena – Painted by Matthew
                           
                           
To make the denominator same, multiply the numerator and denominator of the first term by 9.
                           
                           
                           
Rest of the wall = 
Hence the kevin painted  of the wall.

Answer:
   b.  4x^2 -7x +5
Step-by-step explanation:
When you know a sum and one of its contributors, you can find the other by subtraction. The other trinomial is ...
   (7x^2 -5x +4) - (3x^2 +2x -1)
   = (7 -3)x^2 +(-5 -2)x +(4 -(-1))
   = 4x^2 -7x +5 . . . . . matches B
