Create a poster or transparency that shows the two different methods that your team used to find the area of the regular hexagon in part (b) of problem 8-43. Then, as you listen to other teams present, look for strategiesthat are different than yours. For each one, consider the questions below. •Which geometric toolsdoes this method use? •Would this method help find the area of other regular polygons (like a pentagon or 100-gon)?8-45. Which method presented by teams in problem 8-44 seemed able to help find the area of other regular polygons? Discuss this with your team. Then find the area of the two regular polygons below. If your method does not work, switch to a different method. Assume Cis the center of each polygon.a. b. 8-46. So far, you have found the area of a regular hexagon, nonagon, and decagon. How can you calculate the area of anyregular polygon? Write a Learning Log entry describing a general process for finding the area of a polygon with nsides. 8-47. Beth needs to fertilize her flowerbed, which is in the shape of a regular pentagon. A bag of fertilizer states that it can fertilize up to 150 square feet, but Beth is not sure how many bags of fertilizer she should buy. Beth does know that each side of the pentagon is 15 feet long. Copy the diagram of the regular pentagon below onto your paper. Find the area of the flowerbed and tell Beth how many bags of fertilizer to buy. Explain how you found your answer. 15 ft 5 C 11 C

Answer:

(x + 1)² = 7

Step-by-step explanation:

Given:

-2x = x² - 6

We'll start by rearranging it to solve for zero:

x² + 2x - 6 = 0

The first term is already a perfect square so that's fine.  Normally, if that term had a non-square coefficient, you would need to multiply all terms a value that would change that constant to a perfect square.

Because it's already square (1), we can simply move to the next step, separating the -6 into a value that can be doubled to give us the 2, the coefficient of the second term.  That value will of course be 1, giving us:

x² + 2x + 1 - 1 - 6 = 0

Now can group our perfect square on the left and our constants on the right:

x² + 2x + 1 - 7= 0

x² + 2x + 1 = 7

(x + 1)² = 7

To check our answer, we can solve for x:

x + 1 = ± √7

x = -1 ± √7

x ≈ 1.65, -3.65

Let's try one of those in the original equation:

-2x = x² - 6

-2(1.65) = 1.65² - 6

- 3.3 = 2.72 - 6

-3.3 = -3.28

Good.  Given our rounding that difference of 2/100 is acceptable, so the answer is correct.

Answer:

119.25

Step-by-step explanation:

36/32 simplified is 9/8.

8 + 7(3+11), I'm assuming it's not x.

8 + 7(14) = 106

(9/8)/106 = 9/8*106 = 954/8 = 119.25

Answer:

70 is 125% of 50

Step-by-step explanation:

I hope this helped :)

The percentage value of 70 to  56 is 125% by taking the ratio of 70 to 56 and then converting it to a percentage.

Given that, to find what percent of 70 in 56.

To find out if the percentage of 70 is 56, follow the steps:

Step 1:Find the ratio of the two numbers that is the ratio of  70 and 56 gives:

[tex]70:56 = 70/56[/tex]

Divide both numerator and denominator by 14 yields in:

[tex]= 5/4[/tex]

Step 2: Convert the result of step 1 into decimals by a long division of  5 by 4.

[tex]5/4 = 1.25[/tex]

Step 3: Find the percentage value of the decimal by multiplying the decimal by 100.

[tex]1.25 \times100 = 125[/tex]%

Therefore, the percentage value of 70 to  56 is 125% by taking the ratio of 70 to 56 and then converting it to a percentage.

Answer:

ab=195

Step-by-step explanation:

Answer:

Step-by-step explanation:

Rationalize the denominator of b. So, multiply the numerator and denominator by [tex]\sqrt{x}[/tex]

[tex]b = \frac{(1-2\sqrt{x}) *\sqrt{x}}{\sqrt{x}*\sqrt{x} }=\frac{1*\sqrt{x} -2\sqrt{x} *\sqrt{x} }{\sqrt{x} *\sqrt{x} }\\\\=\frac{\sqrt{x} -2x}{x}\\[/tex]

Now, find a +b

[tex]a +b = \frac{2x+\sqrt{x} }{x}+\frac{\sqrt{x} -2x}{x}\\\\=\frac{2x+\sqrt{x} +\sqrt{x} -2x}{x}[/tex]

Combine like terms

[tex]= \frac{2x-2x+\sqrt{x} +\sqrt{x} }{x}\\\\=\frac{2\sqrt{x} }{x}[/tex]

Now find (a + b)²

(a +b)² = [tex](\frac{2\sqrt{x} }{x})^{2}[/tex]

          [tex]= \frac{2^{2}*(\sqrt{x} )^{2}}{x^{2}}\\\\= \frac{4* x}{x^{2}}\\\\= \frac{4}{x}[/tex]

Hint: [tex]\sqrt{x} *\sqrt{x} =\sqrt{x*x}=x[/tex]
