To write as a polynomial, just multiply every term int he first parenth by every term in the second parentheses.
It is like distributing:
For Example
a2(a-4) - 2a(a-4) + 3(a-4)
a3 - 4a2 - 2a2 + 8a + 3a - 12
Now combine like terms:
a3 - 6a2 + 11a -12 <---- that is your polynomial
now use the above examples and calculate ur question
Kimberly went 5 miles after walking for 2 hours. If Kimberly's rate of travel st
the same, how far would Kimberly go if she walked for 8 hours?
Answer:
20 miles
Step-by-step explanation:
5 miles for every 2 hours. There are 4 groups of 2 hour blocks in 8 hours, so we multiply the 5 miles*4 2 hour blocks (5*4). That leaves us with 20 miles is 8 hours.

Find the volume of a cone with a base diameter of 8 m and a height of 12 m.
Write the exact volume in terms of it, and be sure to include the correct unit in your answer.
Answer:
the formula for the volume of a cone is:
1/3hπr²
1/3×12m×π×8m=100.48m³
In a mathematics class 54, students received an A on the third test, which is 150% of the students who received an A on the second test. How many students received an A on the second test?
10,1 #16
Answer:
Number of students who received A grade on the second test = 36
Step-by-step explanation:
Given that:
Number of students who received A grade on third test = 54
This is 150% of the students who received A on the second test.
Let,
x be the number of students who received A on the second test.
150% of x = 54
[tex]\frac{150}{100}x=54[/tex]
1.5x=54
Dividing both sides by 1.5
[tex]\frac{1.5x}{1.5}=\frac{54}{1.5}\\x=36[/tex]
Hence,
Number of students who received A grade on the second test = 36

Connor is working two summer jobs, making $8 per hour walking dogs and making $12 per hour landscaping. In a given week, he can work a maximum of 15 total hours and must earn no less than $160. If Connor worked 12 hours walking dogs, determine the maximum number of whole hours landscaping that he can work and still meet his requirements. If there are no possible solutions, submit an empty answer.
Answer:
[tex]\mathrm{No\: solutions}[/tex]
Step-by-step explanation:
Since Connor has worked 12 hours walking dogs, he's earned [tex]12\cdot 8 = \$96[/tex] from walking dogs. He still needs to earn [tex]\$160-\$96=\$64[/tex]. As stated in the problem, he makes $12 an hour landscaping, therefore the minimum number of whole hours he must work to fulfill his requirements is [tex]\lceil{ \frac{64}{12} \rceil = 6\: \mathrm{hours}[/tex]. However, the problem states he can only work a maximum of 15 hours. He would have to work [tex]12+6=18[/tex] to fulfill his requirements and therefore he will not be able to meet his requirements with the restrictions given.
Identify the population and the sample.
a. A survey of 1000 U.S. adults found that 83% think credit cards tempt people to buy things they cannot afford.
b. Thirty-eight nurses working in the San Francisco area were surveyed concerning their opinionsof managed health care.
c. A survey of 39 credit cards found that the average annual percentage rate (APR) is 12.83%.
d. A survey of 1205 physicians found that about 60% had considered leaving the practice ofmedicine because they were discouraged over the state of U.S. health care.
In statistics,
Population = Largest set that contains all the individuals or items related to a particular study.Sample = Subset of population.By using above definitions ,
a. Population = all U.S. adults
Sample = 1000 U.S. adults
b. Population = all nurses working in the San Francisco.
Sample = 38 nurses working in the San Francisco.
c. Population = all credit cards
Sample = 39 credit cards
d. Population = all physicians.
Sample = 1205 physicians
Find the smallest non-zero whole number n such that 756n is a perfect cube.
Step-by-step explanation:
756 = 2² * 3³ * 7.
For 756n to be a perfect cube, all of its prime factors must have a power that is a multiple of 3.
How to get from 2² to 2³: Multiply by 2.
3³ has already a power that is a multiple of 3.
How to get from 7 to 7³: Multiply by 7².
Hence n = 2 * 7² = 98.

Adam would like to buy a used car, and collected several data to evaluate the best model (such as age, price, weight, etc.) Thanks to a scatterplot, he established that the relation between age and weight is somewhat linear. He calculated that the correlation between age and weight is 0.512. Describe the association.
Answer: There is a strong association between age and weight.
Step-by-step explanation:
The correlation coefficient (r) is used to describe the relationship between two variables.
[tex]-1\leq r\leq1[/tex]
If r lies between -1 to -0.5 or 0.5 to 1, then there is strong association between them.
Here, Variables: Age and weight.
correlation coefficient = 0.512
That means, there is a strong association between age and weight.

tom scored 23 points in a basketball game. He attempted 15 field goals and 6 free throws. If each successful field goal is 2 points and each successful free throw is 1 point, is it possible he successfully made all 6 of his throws?
Answer:
No
Step-by-step explanation:
The number is odd, so if he makes all 6 the number wouldn't make sense, because for every successful field goal he gets is 2points; so mathematically it wouldn't make sense.
