Answer:
Height = 14.4
Step-by-step explanation:
The diagonals meet at right angles. Interesting property.
The hypotenuse is the side of the rhombus = 15 cm
One of the sides of the small triangles created by the intersection of the diagonals = 24/2 = 12
You can find the other side of the the triangle by using the Pythagorean Theorem
a^2 + b^2 = c^2
c = 15
a = 12
b = ?
12^2 + b^2 = 15^2
144 + b^2 = 225
b^2 = 225 - 144
b^2 = 81
b = 9
The area of this right angle = 9 * 12/2 = 54
There are 4 of them so 4 * 54 = 216
That's the area of the rhombus. 
The h= Area / b
b = 15
h = 216/15
h = 14.4
 
        
             
        
        
        
Answer:
2; -2
Step-by-step explanation:
|7-9| = |-2| = 2
|7|-9= 7 - 9 = -2
 
        
             
        
        
        
Answer: The slope is  -2. 
Step-by-step explanation:
(2,-3) 
(-2,5) 
Using the two given points,  you can find the slope by finding the difference in the y coordinates and diving it by the difference in the x coordinates. 
y coordinates:  -3 - 5= -8 
x coordinates;  2-(-2) = 4  
 Slope:  -8/ 4 = -2
