Answer: 71
Step-by-step explanation: fine the new value and Divided by the old value then multiplied by 100 then you get your answer
 
        
             
        
        
        
y - 4 = -2 ( x - ( -11)) which would simplify to y - 4 = -2 ( x + 11) !!
 
        
             
        
        
        
Answer:
24s^2, 54s^2, 96s^2
Step-by-step explanation:
Let s represent the initial side length of the cube.  Then the area of each face of the cube is A = 6s^2 (recalling that the area of a square of side length s is s^2).
a) Now suppose we double the side length.  The total area of the 6 faces of the cube will now be A = 6(2s)^2, or 24s^2 (a 24 times larger surface area),
b) tripled:  A = 6(3s)^2 = 54x^2
c) quadrupled?  A = 6(4s)^2 = 96s^2
