The second differential of the function is 3/7
Given the differential function 
Differentiate both sides with respect to x implicitly


Get the first derivative at the point (3, 0)

If (x 2y)dy/dx=2x-y what is the value of
the point (3,0)
The answer is B. I hope this helped. Have a great day ! Stay safe!
Assuming the 2nd one is 4a^2 - 20a +25, it is the one you're looking for. It factors to be (2a-5)^2
-15 from both sides then you get 128, 128/8= 16.
The answer is 62 is the andwr
