Answer:
Step-by-step explanation:
Remark
Since the chords of the circle are equal and non intersecting, The 2 bisecting perpendiculars are going to be equal.
Equation
5x = 7x - 8 Subtract 7x from both sides
5x - 7x = - 8
-2x = - 8 Divide by - 2
x = - 8/-2
x = 5
A. The commodity's price will go up after purchase.

Not sure what x' means but
seems to be the reverse distributive property
normally written as
a(b+c)=ab+ac
we can see the similarity
a(x'+y)=ax+ay
distributive property
This is the derivative of S with respect to r, evaluated at r=8.
dS/dr = 8πr
Substituting r=8 into the above gives the answer of 64π.
