The answer is every long.
Step-by-step explanation:
as the figure shows
Answer:x=6
Step-by-step explanation:Step-1 : Multiply the coefficient of the first term by the constant 1 • 18 = 18
Step-2 : Find two factors of 18 whose sum equals the coefficient of the middle term, which is -9 .
-18 + -1 = -19
-9 + -2 = -11
-6 + -3 = -9 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and -3
x2 - 6x - 3x - 18
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-6)
Add up the last 2 terms, pulling out common factors :
3 • (x-6)
Step-5 : Add up the four terms of step 4 :
(x-3) • (x-6)
Which is the desired factorization
Answer:
stuck on that too

The answer to this is 20. You can find the length by using the formula l=a/w
Answer:
Step-by-step explanation:
Hello!
a) The population of interest is the registered voters of the city of Raleigh.
b) This population is finite and its size is 10400 voters.
c) The sample was taken by making a telephone poll, calling 400 registered voters.
d) The sample size is n= 400 voters
The number of people that answered they'd vote for Brown are 151, so the sample proportion of voters that would vote for bron is:
p= 151/400= 0.3775 ≅ 0.38
e) To know how many people is expected to vote for Brown based on the results of the telephone poll you can do the following calculation:
10400*0.38= 3952
Based on the information obtained from the sample, it is expected that only 3952 voters will vote for Brown.
