You just multiply top times top and bottom times bottom and then find a number you can divide into the number and you keep doing that until you can't simplify any more.
Answer:
The answer is C.
Step-by-step explanation:
The simplest form is C.
Circumference (C) = 2 π·r ; where r is the radius = diameter(d)/2
C = 2 π·(14/2)
=2 π·(7)
= 14π
So step one is to distribute the 4x through and the -5 through. After distributing you get 8x^{2}+28x-15x+10. Combine the like terms, 28x and -15x, to get 13x. Your answer is 8x^{2}+13x+10
