The expression (-4x + 9)^2 cannot be equal to (-4x)^2 + 9^2 because it is actually equal to the product of two factors (3 + 2sqrt x) (3- 2 sqrt x). One cannot use obviously distributive property. Hence the answer to this problem should be C. as she did not understand both perfect square trinomial and did not determine the product

First your going to distribute the 3 
3(-3x+15) 
-9x+45
27=6x-9x+15
27=-3x+15
Then you’ll minus 15 from 27
27-15=12
12=3x
X=4
        
             
        
        
        
A.) because for Me you go right 3 and down 3 and so A.) you would go right 3 (5+3) which is 8 then down 3 which is 1.
        
             
        
        
        
45, 51, 52, 58, 61, 63, 66, 72, 74
You're trying to find the second quartile (Q₂), and to find that, you must find the median, and then find the median within the second half of the median :)
Median (Middle Number) : 61
Now, look at 61, and look at 74. What is the median of those numbers in this set?
Q₂ = 66
So, your quartile 2 is 66.
