A)
C(102) = 102^2 – 400 = 10004
</span>C(100) = 100^2 – 400 = 9600
average rate of change = (10004<span>- 9600)/(102 - 100) = 404/2 = 202
</span>B)
C' = 2x = 2 (100) = 200
Research is the way people get their answers most of the time
Answer:
(x - 3)(x + 7)
Step-by-step explanation:
x^2 + 4x - 21
=> x^2 + 7x - 3x - 21
=> x(x + 7) -3(x + 7)
=> (x + 7)(x - 3)
Yes. By all means yes. Its very very possible. In fact it can go in there ten times over.
