X^2-16 is a difference of squares of the form:
(a^2-b^2) which always factors to:
(a+b)(a-b), in this case we have:
(x+4)(x-4), we are told that width is (x+4) so the length is:
(x-4)
25 points is the same integer
Answer:
Step-by-step explanation:
refer to solution in the picture
165/300 -> 55%
This doesn't make much sense though, either the question is out of context or there is some typo because empirical probability is based on results you get from an experiment and actually doing the trial, not on what happens mathematically
9n = 3n-12
-3n= -3n
6n= -12
divide by 6 = -2 =n
to check.. 9 times -2 = -18 soo.. 3 times -2= -6-12= -18
so it is correct!!
hope it helps :)
