14. 5x-2x=12
3x=12
X=4
15. 8b+12=6b-30
2b=42
B=21
Part A:
We have the following expression:
5x2b2 + 14xb2 - 3b2
Rewriting we have:
b2 (5x2 + 14x - 3)
b2 (5x-1) (x + 3)
Part B:
We have the following expression:
x2 - 18x + 81
Rewriting we have:
(x-9) (x-9)
(x-9) ^ 2
Part C:
We have the following expression:
x2 - 121
Rewriting we have:
(x-11) (x + 11)

Answer:
Can you please tell me what is the area of the given triangle?
Answer:
61.70% probability that he or she will be between 23 and 52 years of age
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X between c and d is given by the following formula.

The numbers of full-time wage and salary workers in each age category are almost uniformly distributed by age, with ages ranging from 18 to 65 years.
This means that
. So
(a) what is the probability that he or she will be between 23 and 52 years of age?

61.70% probability that he or she will be between 23 and 52 years of age
