Values needed to complete the X diagram are:
On top -28, On the bottom: -3 and On the sides: -7 and 4.
<h3>What do you mean by 
 factorization?</h3>
An algebraic expression is factorised when it is written as the product of its factors.
The given equation is :
F(x) = x²-3x-28
finding factors,
=  x²-7x+4x-28
= x(x-7) +4(x-7)
= (x-7)(x+4)
Given general equation is ax²+bx+c,
on comparing with  x²-3x-28
a = 1
b = -3
c = -28
ac = 1*(-28) = -28

26 because it’s a supplementary angle. d measures 52 degrees and 52/2 is 26.
        
                    
             
        
        
        
Yes there are 8 flute players
The equation is 
4+F=12 
Subtract 4 from both sides you have F=8
        
             
        
        
        
Answer:
576 cm^3
Step-by-step explanation:
Express this volume formula as V = π r^2 h, where the " ^ " symbol indicates exponentiation.  Substitute 4 for r (this is half the diameter), 12 cm for h, and 3 for π:  V = 3*(4)^2*12 cm^3, or V = 576 cm^3.
