10x^2-6x^2 = 4x^2
-64-36 = 100
4x^2 -100 = 0
(2x -10)(2x+10)
X = 2/10 and x = - 2/10
        
             
        
        
        
Step-by-step explanation:
I'll do the first problem as an example.
∠P and ∠H both have one mark.  That means they're congruent.
∠T and ∠G both have two marks.  So they're congruent.
∠W and ∠D both have three marks.  So they're congruent.
So we can write a congruence statement:
ΔPTW ≅ ΔHGD
We can write more congruence statements by rearranging the letter, provided that corresponding pairs have the same position (P is in the same place as H, etc.).  For example:
ΔWPT ≅ ΔDHG
ΔTWP ≅ ΔGDH
 
        
             
        
        
        
the initial statement is:

and then:

So the second statement is false because f should be multiply by e, not by d so is option C)
 
        
             
        
        
        
Answer: 29.6
Step-by-step explanation:
i got it right
 
        
             
        
        
        
= 6.37 * 10^4 = 637 * 10^2 = 63700
In short, Your Answer would be Option A
Hope this helps!
