(a) 4, ·b) , (c) , (d)
using the slope m of a line = tanΘ = (difference in vertical )/(difference in horizontal ) between 2 points on the line
using the endpoints of each line, then
(a) tan Θ = = 4
(b) tan Θ =
(c) tan Θ = =
(d) tan Θ =
A=3 Root(25+10) Root (5a^2)
Using this formula
Your answer is 3.17x10^5
The correct answer is 28.27 <span />
Normally You would need to simplify all of them, to see what their values are like.
Already from the start, however, we can see that 9n + 3 + 2 and 9n + 11 isnt the same value. Based on this, we should only need to simplify one of the other, to get either 9n + 5 or 9n + 11.
Lets pick the upper one.
(4n + 3) + 5n + 8 - 6
4n + 3 +5n + 2
9n + 5.
This indicated that 9n+11 is the odd one.
To make sure, we can solve the next one:
(4n + 5n) + (3 + 8 - 6)
9n + 5
Which indicated the same thing.
9n+11 is the "outsider", which means:
9n + 11 is the correct answer for this task.
Answer:
18. 8x+40
8. 2hours 30 minutes
Step-by-step explanation:
8. 8x2= 16
8 divided by 2 is 4
4+16= 20
4mph = 30 minutes
8mph = 1 hour
8+8+4= 2 hours and 30 minutes
