Answer: 
Step-by-step explanation:
Given : Sample size : 
, which is a small sample (, 30) so we use t-test.
Sample mean : 
Standard deviation : 
Significance level : 
Critical value : 
The confidence interval for population mean is given by :-
Hence, a 95% confidence interval for the population mean 
=
X=hamburgers
y=hotdogs
3y+2x=8.00
AND
2y+3x=8.25
Now we've got a system of equations!
Choose a method to solve it, and I think you'll be good from there.

Answer:
Step-by-step explanation:
If you have written the question correctly, then you don't need to factor it. You only need to remove the brackets.
x + 1 + 6x + 6 + 8
7x + 15 is your final answer.
However, I think the question is
(x + 1)^2 + 6(x + 1) + 8
Let y = x + 1
y^2 + 6y + 8
(y + 2)(y + 4)
(x + 1 + 2 ) ( x + 1 + 4)
(x + 3)(x + 5)
