The answer would be 9(8b+5)
this is how you do it...
1. find the GCF of both numbers in this one the GCF would be 9
now, what do you multiply 9 by to get 72... 8, so 8 would go into the parenthesis and because there is a variable there which is 'b' the 8 would become '8b' now what do you multiply 9 with to get 45? '5' so you would add 5 into the parenthesis and that would be your answer!
Hope this helped! :D
Answer:
Option d.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error is:
79 percent of adults age 18 years and older in the United States use the Internet.
This means that 
98% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
Which of the following should be used to find the sample size (n) needed?
We have to find n for which 
So the equation is:
Option d.
Q(3) = -2(3)+2 = -4
r(q(3)) = (-4)^2-1 = 15
16-3y because you distribute through the parenthesis frist and then you solve for your answer
The Range is going to be -10, -7, -4, -1, 2
