Answer:
8n + 14 is the product
Step-by-step explanation:
Use the distributive property to solve:
( 4n +7 ) 2
8n + 14
Answer: 14.4 h
The speed is :
![miles/h\\](https://tex.z-dn.net/?f=miles%2Fh%5C%5C)
The time it takes to travel 279 miles :
![t'=\frac{d}{v} =\frac{279}{19.46} =14.4 hours](https://tex.z-dn.net/?f=t%27%3D%5Cfrac%7Bd%7D%7Bv%7D%20%3D%5Cfrac%7B279%7D%7B19.46%7D%20%3D14.4%20hours)
Well there has to be a right angle in there somewhere as the pole must be perpendicular to the ground.
Using the sine rule:
sinA/a = sinB/b where a = 10, A = 90, b = 5√3, B = B
Re-arrange for B, B = arcsin (b(sinA)/a)
B = arcsin(5√3(sin90)/10)
B = 60 degrees.
Answer is C
