Answer:

Step-by-step explanation:
2 + m
Rewrite with variable first.
m + 2
m + 2
Can’t be simplified further.
m - (-2) 
Distribute negative sign.
m + 2
-2-m
Rewrite with variable first.
-m - 2 
The last expression is not equivalent to m+2.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Let the equation of the cosine function is,
y = Acos(Bx)
From the graph attached,
A = Amplitude = 
    = 1
B = 
B = 
B = 
B = 4
Therefore, equation of the cosine wave given in the graph will be,
y = 1.Cos(4x)
y = Cos(4x)
 
        
                    
             
        
        
        
Answer:
 FALSE
Step-by-step explanation:
the correct answer is FALSE
A matrix is said to be orthogonal when it is  multiplied by its own transpose then the matrix comes out to be Identity.
                                        
the basic condition for a matrix to be diagonalizable is that the matrix should be symmetric.
but an orthogonal matrix is not necessarily symmetric so, the statement is false.
 
        
             
        
        
        
Answer:
Actually, there are two. They are the Parallelogram Opposite Sides Theorem and the Parallelogram Opposite Angles Theorem.
Step-by-step explanation:
POST means that if opposite sides of a quadrilateral are the same, it's a parallelogram.
POAT means that if opposite sides of a quadrilateral are the same, it's a parallelogram.
A quadrilateral has to meet both of these theorems to be a parallelogram. 
 
        
             
        
        
        
<span>8(x-3.7)
To find this, you must first use the distributive property.
8 • x = 8x
8 • -3.7 = -29.6
</span>8(x-3.7) = 8x - 29.6
Since there is no way to completely solve this since it's only an expression and not an equation, this is in simplest form.
