Answer:
Factors for 8: 1, 2, 4, 8
Factors for 9: 1, 3, 9
So 8 has more factors
Start by identifying any factor of 50 and then rewriting 50 to include that one factor and another:
50 = 5 * 10 5 is prime, but 10 is not. Thus, factor 10:
50 = 5 * 5 * 2 This is 50 as a product of its prime factors 5, 5 and 2.
A) a=the initial value ($1650)
b=1-percent of decrease (0.81 or 81%)
B) About 3 years
The answer is 9, hope this helped <3
Use the Pythagorean therm , you know the a^2+b^2=c^2
