In every right triangle, if you add up the squares of the two 
shorter sides, you get the square of the longest side. If you 
don't then it's not a right triangle.
10² = 100
24² = 576
100 + 576 = 676
676 is the square of 26.  
It's NOT the square of 28.
So 10 - 24 - 28 is not a right triangle.
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
Hi there!
Slope-intercept form:  where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x=0)
 where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x=0)
<u>1) Determine the slope (</u><u><em>m</em></u><u>)</u>
 where two points that fall on the line are
 where two points that fall on the line are  and
 and 
Given the graph, we determine which points we could use. For example, we could use the two points  and
 and  :
:

Therefore, the slope of the line is -6. Plug this into  :
:

<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>
Recall that the y-intercept occurs when x=0. Given the point (0,2), we know that the y-intercept is 2. Plug this into  :
:

I hope this helps!
 
        
             
        
        
        
D=6 or 3x2 and R= 3.14 should be correct! hope this helps                                                                                                                                                                                                                                                          
 
        
             
        
        
        
First, factor out the common factor 5.
<span>15y^2-50y+35 =
= 5(3y^2 - 10y + 7)
Now we need to factor the trinomial.
3 can be factored as 3 * 1
7 can be factored as 1 * 7 or (-1) * (-7)
Since the middle term is negative, we need to use -1 and -7 as the factors of 7
= 5(3y - 7)(y - 1)

Answer:
a.) x + 10 
b.) x - 6 
( i think ) 
Step-by-step explanation:
adeline is x years old so they can be any age really . 10 , 12 , 27 . etc . 
in ten years she will be her age now ,, PLUS another ten years so it is x + 10
same for part b . except it is six years ago therefore take away . x - 6
