Step-by-step explanation:
the sum of the angles = 360
8x+2 + 2x + 14 + 3x -4 +5x + 5 = 360
18x +17 = 360
18x = 343
x = 19.1
angles are:
154.8
52.2 smallest (2x + 14)
53.3
105.5
Answer:
![\frac{7\sqrt{x} }{x}](https://tex.z-dn.net/?f=%5Cfrac%7B7%5Csqrt%7Bx%7D%20%7D%7Bx%7D)
Step-by-step explanation:
To simplify 7/√x, we need to rationalize:
![\frac{7}{\sqrt{x} } (\frac{\sqrt{x} }{\sqrt{x} } )](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B%5Csqrt%7Bx%7D%20%7D%20%28%5Cfrac%7B%5Csqrt%7Bx%7D%20%7D%7B%5Csqrt%7Bx%7D%20%7D%20%29)
When we multiply the 2, we should get our answer:
![\frac{7\sqrt{x} }{x}](https://tex.z-dn.net/?f=%5Cfrac%7B7%5Csqrt%7Bx%7D%20%7D%7Bx%7D)
Answer:
The midpoint is (1, 4.5)
Step-by-step explanation:
To find the midpoint, take the coordinates for the two endpoints and add the x's and divide by two. Then add the y's and divide by two. R has coordinates (-4,0) and B is (6,9). On this particular question when we just do half of the problem we can pick out the correct answer from the multiple choice list. -4 + 6 is 2. And divided by 2 is
2/2 is 1 there is only one choice that has an x that is 1. It doesn't hurt, nor take much time to confirm with the y's. 0+9 is 9. And 9/2 is 4.5.
So the midpoint is (1, 4.5)
Answer:
x=5
Step-by-step explanation:
40/x=32/4
160=32x
160/32=32x/32
5=x
