28, because when you divide you get about 28. good luck!
 
        
                    
             
        
        
        
Hello from MrBillDoesMath!
Answer:
See Discussion below
Discussion:
A function f is even if f(-x) = f(x)
f(x)                               f(-x)                                  Are they equal?
----------------------------------------------------------------------------------------
-x^8 + 2x^6-5x           -(-x)^8 + 2(-x)^6 + 5x         No
3 abs(x) - 4                 3 abs(-x) -4                       Yes
log5 x^2                     log5 (-x)^2                        Yes
(6x)^ (1/7)                     (-6x)^(1/7)                          No
e^(x^2-x)                     e^( (-x)^2+x)                      No
(x^8 +5x^2)^(-1)           ( (-x)^8 + 5 (-x)^2) ^(-1)      Yes
Answers with Yes, above are even functions.

Answer:
6.)  angle 1 = 61 degrees.  angle 2 = 61 degrees. . 7.) angle 1 = 44 degrees
angle 2 = 44 degrees
Step-by-step explanation:
main reason is that because of  Alternate Interior angles theorem  angle 1 = angle 2 
for both questions 6 and 7.
Also  the angles that form a straight line sum to 180 degrees
so 61 + 58 + 61 = 180
and for 7
90 = 46 + 44
