 Explanation: A diagonal of a rectangle cuts the rectangle into 2 right triangles with sides equal to the sides of the rectangle and with a hypotenuse that is the diagonal. All you need to do is use the pythagorean theorem: where a and b are the sides of the rectangle and c is the length of the diagonal.
 
        
             
        
        
        
Answer:
The reasoning is  a deductive. 
   The reason is because the pattern of  thought is logical, here, scientific methods ( i.e mathematically obtaining and comparing the density of the coin and the  gold ) are used to support the conclusion.
Step-by-step explanation:
Gnerally the reasoning is  a deductive. 
   The reason is because the pattern of  thought is logical and scientific methods (eg mathematical equation (formula for density)) are applied to arrive at the  conclusion.
 
        
             
        
        
        
Answer: Point F is at location (-4, -5)
The x and y axis meet at the origin (0,0)
Start at the origin and move 4 units to the left. This means the x coordinate is x = -4
Then move 5 units down so the y coordinate is y = -5
Put together (x,y) = (-4, -5) describes where point F is located.
