For the triangle, x is 12 units long.
Step-by-step explanation:
Step 1:
According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
The hypotenuse is the side which is the longest in the triangle and is always opposite the right angle.
In the given triangle, the hypotenuse is 13 units long. The other two sides measure 5 units and x units.
Step 2:
By substituting the known values, we get



Rounding this off to the nearest hundred, we get that x is 12 units long.
 
        
             
        
        
        
Answer:
6x^3+11x^2-14x+12
Step-by-step explanation:
We just simply add like terms (terms with same power of x):

Like terms are in brackets now 
So you just simplify now to give you:

 
        
             
        
        
        
Answer:
81.5, 9, 180
Step-by-step explanation:
28.
c=9
9x9=81
a=1/2
81+1/2=81.5
29.
9x1/2=4.5
4.5x2=9
30.
15x15=225
9x5=45
225-45=180
hope this helps!!!
