Answer:
w = 7 inches
Step-by-step explanation:
length = n
width = n/2
Perimeter = 2n + 2(n/2)
42 = 2n + n
42 = 3n
n = 14
width = 14/2 = 7

2*10⁴-7³= please help
Answer:
19657
Step-by-step explanation:
By PEMDAS, we know we have to calculate the exponents first, then multiply the 2, and then subtract the 7³
2*10⁴ = 20000
20000 - 7³ = 19657
What is the area of the regular heptagon shown below? (Round your answer
to the nearest whole number.)
231
22.15
A. 3566 sq. units
B. 1528 sq. units
C. 1783 sq. units
D. 3057 sq. units
y’all help please
Answer:
C
Step-by-step explanation:
A heptagon is a polygon with 7 triangles. (a)
Thus, The area (A) will be = 7a
[tex]The \ area \ of \ \ triangle \ = (1/2) \times b \times h[/tex]
where;
b = base
h = height
So;
[tex]7a = \dfrac{1}{2}(bh)[/tex]
where;
b = 22.15 unit and h = 23 unit
∴
[tex]A = \dfrac{7 \times b \times h}{2} \\ \\ A = \dfrac{7 \times 22.15 \times 23}{2} \\ \\ A = 1783.07 \ sq. units \\ \\ A \simeq 1783 \ sq. units \\ \\[/tex]

Complete the problem using the following steps to find the factored form of the polynomial.
1. Find all possible rational roots.
2. Use Descartes' rule of signs to determine the possible number of positive, negative, and
complex roots.
3. Use synthetic division and the quadratic formula to find all roots.
4. Write the polynomial in factored form.
Show ALL work for your steps.
f(x) = x^3 - 4x^2 - 3x + 12

There are five sign changes, so there are five or, counting down in pairs, three or one negative solutions. Then my answer is:There are two or zero positive solutions, and five, three, or one negative solutions.In the above example, the maximum number of positive solutions (two) and the maximum number of negative solutions (five) added up to the leading degree (seven). It will always be true that the sum of the possible numbers of positive and negative solutions will be equal to the degree of the polynomial, or two less, or four less, or....This can be helpful for checking your work. For instance, if I had come up with a maximum answer of "two" for the possible positive solutions in the above example but had come up with only, say, "four" for the possible negative solutions, then I would have known that I had made a mistake somewhere, because 2 + 4 does not equal 7, or 5, or 3, or 1
There are four, two, or zero positive roots, and zero negative roots.
Descartes' Rule of Signs can be useful for helping you figure out (if you don't have a graphing calculator that can show you) where to look for the zeroes of a polynomial. For instance, suppose the Rational Roots Test gives you a long list of potential zeroes, you've found one negative zero, and the Rule of Signs says that there is at most one negative root. Then you know that you've found every possible negative root (rational or otherwise), so you should now start looking at potential positive roots.Similarly, if you've found, say, two positive solutions, and the Rule of Signs says that you should have, say, five or three or one positive solutions, then you know that, since you've found two, there is at least one more (to take you up to three), and maybe three more (to take you up to five), so you should keep looking for a positive solution.

some soiled goods are sold for 2 /5 of their original price. what will be the selling price of a pair of trouser originally Costing#850.00
Answer:
The selling price of the goods is #340.00
Step-by-step explanation:
Given;
original price, P = #850.00
the new cost = 2/ 5 of the original price
The selling price of the goods is calculated as follows;
[tex]= \frac{2}{5} \ \times \#850\\\\ = \# 340[/tex]
Therefore, the selling price of the goods is #340.00

!!!!!!!!WILL MARK BRAINLIEST!!!!!!!!!!!! A school board is interested in whether high school students would like to shift the school day forward by 30 minutes. They decide to conduct a survey and randomly select students who are involved in extracurricular activities. Which statement is true? A. The survey results are most at risk for nonresponse bias. B. The survey results are most at risk for undercoverage. C. The survey results are most at risk for students not being able to answer honestly. D. The survey results are not at risk for any bias.
Based on the information given, the survey results are most at risk for undercoverage.
In this case, the right sample of the students to be collected should have been the high school students. Every student ought to have an equal chance of being picked.
Selection of those that are involved in extracurricular activities shows bias. Therefore, this will bring about an undercoverage.
In conclusion, the correct option is B.

Answer:
x=44
Step-by-step explanation:
alright to make this easy we have to find out all of the angles values. If you see those little lines, then they are indicating that the opposite angles are similar. so angles b and d are equal to 34. in order for a triangle to be true all of the angles added up have to equal 180 so to find the last angle we do 180 -34 -34 which equals 112. That is the angle of c on the bottom triangle. The angle next to is is suplementary meaning that those two angles added together will equal 180. If one angle is 112 we just subtract 112 from 180 to get the other angle which is 68. Once again we have the two little lines indicating that the two angles are the same. Again we do 180 - 68 - 68 which is 44. Therefore x =44
