1260-360-360-360=180
Therefore,180
Arc length, (s)=(radius, r)(central angle, q)
s=rq
q=s/r
q=4/10
q=2/5, or 0.4 radians
Answer:
![\frac{3x+7}{x+2}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%2B7%7D%7Bx%2B2%7D)
Step-by-step explanation:
Given the following question:
![\frac{(x+4)(3x+7)}{(x+4)(x+2) }](https://tex.z-dn.net/?f=%5Cfrac%7B%28x%2B4%29%283x%2B7%29%7D%7B%28x%2B4%29%28x%2B2%29%20%7D)
In order to simplify the expression given we can only cancel the common factor which is four.
![\frac{(x+4)(3x+7)}{(x+4)(x+2) }](https://tex.z-dn.net/?f=%5Cfrac%7B%28x%2B4%29%283x%2B7%29%7D%7B%28x%2B4%29%28x%2B2%29%20%7D)
![cf=(x+4)](https://tex.z-dn.net/?f=cf%3D%28x%2B4%29)
![\frac{x+4}{x+4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B4%7D%7Bx%2B4%7D)
![=\frac{3x+7}{x+2}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B3x%2B7%7D%7Bx%2B2%7D)
Cannot be simplified further due to it not having any more common factors. Your answer is "3x + 7 / x + 2."
Hope this helps.
They want you to write the number in index form.
The number is 5N^2, where N = 3 x 5^2 x x^3
So:
5N^2 = 5 x (3 x 5^2 x x^3)^2
= 5 x (3^2 x 5^4 x x^6)
= 3^2 x 5^5 x x^6
or a bit neater looking: 3² ₓ 5⁵ ₓ x⁶
