A square again
Lets take a is side of a square.
if u take parts of square from mid point and measure distance or length of any sides that would be a/2
then use Pythagorean theorem to solve hypotenuse u will get all length of small quadrilateral a/√2.same for all sides.
I see that will be square again
        
             
        
        
        
Answer:
1. Sample space: red or blue 
2. Red: 3/5,   Blue 2/5
3. 60% probability of selecting a red, 40 percent probability
4. 1 more blue 
Step-by-step explanation:
3. 3/5 x 2 = 6/10 --> 60%
4. 5 total, 3 red, 2 blue (+ 1 blue) = 6 total, 3 red, 3 blue
 
        
             
        
        
        
Answer:
The fourth law of exponents says that "any value other than zero brought to an exponent of zero is equal to one". ... However, zero to the zero gets an error with the calculator, thus any value other than zero brought to an exponent of zero is equal to one, this proves fourth law of exponents.
 
        
                    
             
        
        
        
4x4=16. So think of it like this now..
3x-16=65
Add 16 in each side and you get 3x=81. Divide 3 with 81 and should be 27, or x=27. 
Then you check it by putting in the #'s
3(27)-4(4)=65
81-16=65
65=65 ✔️
