Answer:
x^2+16x+64 is a perfect square
that is (x+a)^2=x^2+2ax+a^2
compare the coefficients of the x term
--> 2a=16 --> a=8
---> x^2+16a+64=(x+8)^2
plz mark me as brainliest :)
 
        
             
        
        
        
Answer:
The answer would be 
H = A over L times W
Step-by-step explanation:
This is because, when you multiply the L, W, and H you end up getting A. This means that A is the biggest number. We automatically can tell that H is what were looking for so putting those two things together we have this: H = A over ???
The ??? would have to be L times W because those are the only things left and they get multiplied together which in the end leaves us with
H = A over L times w
aka
H=A/LxW

It would have to be number 2 if it's a dotted line, all the other options are incorrect unless you made a mistake with one or two of the symbols.
