SA = 2lw + 2lh + 2hw
SA = 2(15)(2) + 2(15)(6) + 2(6)(2)
SA = 60 + 180 + 24
SA = 264
        
             
        
        
        
Answer:
answer below
Step-by-step explanation:
ABCDE go through dilation over center (6 , -2) with factor of 1/2 to FGHIJ
AB // FG slope: -2 , √20:√5 = 2: 1
BC // GH // X axis 8:4 = 2:1
CD // HI, slope= 1 , √8:√2 = 2:1
DE // IJ // x axis, 4:2 = 2:1
EA // JF // y axis, 2:1

Hi there! 
Your question: 
Sales fall from 300 per week to 270 per week what's the percentage change?
My answer:
The formula for calculating percent change is as follows: 
[(y2 - y1)/y1]*100=your percent change 
y2= first value 
y1=second value 
Plug the numbers in: 
[(300-270)/300]*100
[30/300]*100
0.1*100
10 
Therefore, the percent change is 10%
Hope this helps! Let me know if it's incorrect so I can fix it:)
