Answer: 
Step-by-step explanation:
The Greatest Common Factor (GCF) of a polynomial is defined as the largest monomial that is a factor of all the terms of the polynomial.
In this case, given this polynomial:

You can factor out the Greatest Common Factor applying this procedure:
1. Write the terms of the polynomial in prime factor form:

2. Identify the factors the terms have in common (this will be the Greatest Common Factor). In this case this is:

3. Finally, rewrite the expression in factor form:

Answer:
3mph
Step-by-step explanation:
notice that for every 1 hr, 3 miles is been travelled
Answer:
For this case from the info given we have the estimated proportion of people who thinks that Children of illegal inmigrants should be able to attend public school
So then the value reported 45% or in fraction 0.45 represent the sample proportion fo interest.

And this value was calculated with a sample of n =1000 people.
And X for this case is 450, because 0.45*1000=450
The real interest is on the population proportion
of people who thinks that Children of illegal inmigrants should be able to attend public school
Step-by-step explanation:
Assuming the following question : "Give the relevant proportion using correct notation. Your answer should be an expression composed of symbols: A recent headline states that 45% Think Children of illegal inmigrants Should Be Able to Attend Public School. The report gives the results of a survey of 1000 randomly selected likely voters in the US."
For this case from the info given we have the estimated proportion of people who thinks that Children of illegal inmigrants should be able to attend public school
So then the value reported 45% or in fraction 0.45 represent the sample proportion fo interest.

And this value was calculated with a sample of n =1000 people.
And X for this case is 450, because 0.45*1000=450
The real interest is on the population proportion
of people who thinks that Children of illegal inmigrants should be able to attend public school
4x^2(x-3)-5(x-3)
(x-3)(4x^2-5)
