False
because 
r=2
so 
an=a1r^(n-1)
a4=(-1)(2^(4-1))
 =(-1)(2^3)
 =(-1)(8)
 =-8 
so a4 equals -8 not -6
        
             
        
        
        
Since the whole thing is 24x+8, it is divided in 2 parts so both of those must be equal to the whole one. You get:
14x-2+70=24x+8 
10x=60
x=6
        
             
        
        
        
The quotient is the answer to a division problem.  And the factors are the numbers u are multiplying.
        
             
        
        
        
Answer: F.) 7 triangles
Step-by-step explanation:
Congruent means completely equal in side lengths and angles. Think of this weird figure like 4 triangles that are see through and are covering a diamond underneath
Of those 4 "see through triangles", there are 3 equal to ΔABC
Now on the diamond underneath, there is another 4. Its hard to actually explain what I mean, but take two triangles from that dimaond. Theyre gonna be congruent to ΔABC.
That's 4 + 3 = 7 total triangles
 
        
             
        
        
        
This can be expanded through the tangent angle addition formula:
tan(α+β)=tanα+tanβ1−tan -α + tanβ
 
Thus,tan(x+y)=tanx+tany1−tan x tany
Hope it helps you
