Answer: Gear B turns 90 times when gear A turns 60 times
Step-by-step explanation: To solve this you just 30x3=90
6x² + 48x + 96
6(x² + 8x + 16)
6(x + 4)(x + 4) is your polynomial fully factored so I'm guessing the binomial you're looking for is (x + 4).
CosB= 7/25
tanB= 24/7
sinB= 24/25
2,300 meters is the answer to your question.
The difference between 90% and 72% is 18%
