Answer:
1.x^2
2.x+8
3.x
4. 8x
Step-by-step explanation:
Length of old is x inches. 
Because it is square we have that area of the old canvas : 
When we read : width of new is increased by 8 so : x+8
Length is x.
The difference of areas:

To make 70% she has completed 7 out of 10 shots. for her to get 75% she would need 3 out of 4 each time.
        
                    
             
        
        
        
Given:
Original or base : 40
New amount : 72
We need to find the difference of the new amount and the original amount
72 - 40 = 32
We then divide the difference by the original amount
32/40 = 0.80
We multiply the quotient by 100%
0.80 x 100% = 80%
The percentage of change is 80%
