Answer:
10
Step-by-step explanation:
So the unit rate in this situation is how many times Jazmine spun around in 1 minute, since unit is always 1. To find the answer you divide 20 by 2 which is equal to 10. She spun around 10 times in 1 minute, and 20 times in 2 minutes.
(x-12)(x-12) would factor to x²-24x+144.
(x-12)(x+12) = x²+144
Option C is correct :)
I think the answer would be 1.
