Answer:
D. 28x + 14 + 3 = - 67
Step-by-step explanation:
Given 7 ( 4x + 2 ) + 3 = - 67
our first step would be to distribute the 7
7 * 4x = 28x
7 * 2 = 14
we would be left with 28x + 14 + 3 = -67 which corresponds with "D"
Answer:
The answer I have to say would be D. Please correct me if I am wrong but I am positive with my answer!

Answer:
dy/dx = (4 (x + y)^3 - y) / ( x - 4(x + y)^3).
Step-by-step explanation:
xy = (x + y)^4
Using implicit differentiation:
x dy/dx + y*1 = 4 (x + y)^3 * (1 + dy/dx)
x dy/dx + y = 4 (x + y)^3 + 4 dy/dx (x + y)^3
x dy/dx - 4 dy/dx (x + y)^3 = 4 (x + y)^3 - y
dy/dx( x - 4(x + y)^3) = 4 (x + y)^3 - y
dy/dx = (4 (x + y)^3 - y) / ( x - 4(x + y)^3)
