Step-by-step explanation:
Answer:
D
Step-by-step explanation:
The function will be zero when the numerator is equal to 0. So, set the numerator equal to 0 and solve:

I will use the quadratic formula:

Therefore, x = 9 is a 0. Let's check with subtracted root now:

It appears 0 is also a root.
Therefore, the answer is D.
Answer: 2 7/10
Step-by-step explanation:
If i did the math correctly one number is 50
19 has two factors: 1, 19
21 has four factors: 1, 3, 7, 21
23 has two factors: 1, 23
And we need a number that has more than four factors and is greater than 25.
Factors of 50- 1, 2, 5, 10, 25, 50
50has six factors and is greater than 25.
If we want to has 100 in the denominator we have to divide numerator and denominator by 2. Then total value of fraction doesnt change.

Now read the fraction, its 23 hundreds, now just write as decimal, so,
0.23
