Answer:
1001 
1 
Step-by-step explanation:
If a quadratic function crosses the x-axis twice, it has two solutions. For a quadratic function in  with discriminant
 with discriminant  , the following is true:
, the following is true:
- If  , then the quadratic has two real solutions , then the quadratic has two real solutions
- If  , then the quadratic has one real solution , then the quadratic has one real solution
- If  , then the quadratic has no real solutions , then the quadratic has no real solutions
Therefore, in order to have two solutions, a quadratic's discriminant must be larger than 0. The only two answer choices that satisfy this are 1001 and 1.
 
        
             
        
        
        
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:
Old canvas : A1=
New canvas : 
Now we can find A2-A1:

 
        
             
        
        
        
So to find the answer u must multiply 20 x 5= 100
        
             
        
        
        
95% C.I. = 0.62 + or - 1.96 * sqrt[0.62(1 - 0.62)/34,271] = 0.62 + or - sqrt(6.875 x 10^-6) = 0.62 + or - 0.002622 = 0.62 - 0.002622 to 0.62 + 0.002622 = 0.6174 to 0.6226 = 61.74% to 62.26%.
        
             
        
        
        
2 would most like be doubled and be 4 I think...
