Answer:
53.1
Step-by-step explanation:
I used my protractor and that is what I got there is no detailed explanation that I came up with
Here’s a photo explaining the answer.Im assuming the leanght is x plus 4 and breadth is x
<span>So we want to know the order from the least to greatest for 1/2, 5/6, 2/7 and 4 / 2. Lets turn them into decimal numbers: 1 / 2 = 0.5, 5 / 6 = 0.83334, 2 / 7 = 0.2857 and 4 / 2 = 2. So the order frome the least to greatest is: 2/7 < 1/2 < 5/6 < 4/2. And that is the answer B</span>
We already got
f(x)= a(x-2)(x-3)(x-5)
We got ![a=\frac{1}{6}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B1%7D%7B6%7D)
first we multiply the parenthesis in f(x)
f(x)= a(x-2)(x-3)(x-5)
![f(x)= a(x^2-5x+6)(x-5)](https://tex.z-dn.net/?f=f%28x%29%3D%20a%28x%5E2-5x%2B6%29%28x-5%29)
![f(x) = a(x^3 - 10 x^2 + 31 x - 30)](https://tex.z-dn.net/?f=f%28x%29%20%3D%20a%28x%5E3%20-%2010%20x%5E2%20%2B%2031%20x%20-%2030%29)
Replace the value of 'a'
![f(x) = \frac{1}{6}(x^3 - 10 x^2 + 31 x - 30)](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7B1%7D%7B6%7D%28x%5E3%20-%2010%20x%5E2%20%2B%2031%20x%20-%2030%29)
Multiply 1/16 inside the parenthesis
![f(x) = \frac{1}{6}x^3 - \frac{5}{3} x^2 + \frac{31}{6} x - 5](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7B1%7D%7B6%7Dx%5E3%20-%20%5Cfrac%7B5%7D%7B3%7D%20x%5E2%20%2B%20%5Cfrac%7B31%7D%7B6%7D%20x%20-%205)
Answer:
E; 8x9 is equal to 72 which estimated is 70
