First, expand to make it easier
y=x(x^2+5)(x^2+5)
y=x(x^4+10x^2+25)
y=x^5+10x^3+25x
differentiation
y'=5x^4+30x^2+25 is the derivitive
Step-by-step explanation:
b. what is the perimeter of the rectangle in terms of k?
Answer:
step 2
Step-by-step explanation:
The student first made an error in the step 2.
Because if we simplify the equation A in step 1, we should distribute the right side of the equation following the rule a(b-c) = a*b +a*(-c)
So, it would be
–7y = (-7)*(16)+(-7)*(-2z)
=> -7y = -112 + 14z
x =-5

1) Since the Formula of the Midpoint is:
2) So Let's plug it into the formula the values, for A, and B
3) So the x coordinate of the Midpoint is x =-5
Answer:
I think the answer would be A .
