Answer:
x=5 and x=-5
Step-by-step explanation:
1. first you would subtract 6 from both sides to set the equation = to zero.
2. The equation would then be x^2-25=0.
3. that is a difference of two squares polynomial. So when you factor it, it is (x+5)(x-5)=0
4. by the zero product property, the roots are 5 and -5.
Answer
a. True
Step-by-step explanation:
Based on this survey we estimate that about 
of the college students smokes. And a 
confidence interval is ![[15.1\% ; 21.6\%]](https://tex.z-dn.net/?f=%5B15.1%5C%25%20%3B%2021.6%5C%25%5D)
. So we know that 
our estimative for the smoking rate is in the confidence interval with certainty. We also know the estimative for the smoking rate in the general population is 
. So we can write the two possible hypothesis:
Smoking rate is equal to .
Smoking rate is not equal to .
We will reject the null hypothesis 
if the estimate doesn't fall into the confidence interval for the college students smoking rate.
Since this condition holds we reject the null hypothesis. So with certainty we say that the smoking rate for the general population is different than the smoking rate for the college students.
To find the largest possible rectangular area, you must find the two highest common factors, which are, in this case is 20 x 10. therefore the answer is 20m x 10m
