Answer:
17
Step-by-step explanation:
17 is prime, so has only 1 and itself as (positive integer) divisors.
12 has positive divisors 1, 2, 3, 4, 6, 12
14 has positive divisors 1, 2, 7, 14
15 has positive divisors 1, 3, 5, 15

<em>Comment on "factors"</em>
Sometimes, we make a distinction between (prime) factors and divisors. A factor is often considered to be a prime number that is a divisor, so 1 is not included. (Here, that would mean 14 and 15 have two factors, but 17 does not.) A divisor is considered to be any integer that gives the number when multiplied by another integer. When factoring polynomials, we often also include negative integers among the divisors of the numbers we're concerned with.
Answer:
39.5
Step-by-step explanation:
25*1.58
Answer:
x= ±2 sqrt(3)
Step-by-step explanation:
4x^2+11= 59
Subtract 11 from each side
4x^2+11-11= 59-11
4x^2 = 48
Divide by 4
4/4x^2 = 48/4
x^2 = 12
Take the square root of each side
sqrt(x^2) = sqrt(12)
x = ±sqrt(4*3)
x= ±2 sqrt(3)
Answer:92.53
Step-by-step explanation:95×2.6℅=2.47
95-2.47=92.53
Answer:
The mean would be 82
Step-by-step explanation:
To find the mean you add up all the numbers.
Then you divide that be the amount of numbers are given to you.
And that is how you find the mean.
Sorry if it is wrong I'm tired.
