Answer:
DC = 3
Step-by-step explanation:
Based on triangle similarity theorem, we would have the following equation:
Plug in the values
Cross multiply
3(9 + DC) = 9×4
27 + 3DC = 36
Subtract 27 from each side
3DC = 36 - 27
3DC = 9
Divide both sides by 3
DC = 9/3
DC = 3
Rule: (a/b)/(c/d)=(a/b)*(d/c)
(5/14)/(3/4)
(5/14)(4/3)
(5*4)/(14*3)
20/42
10/21
Answer: 6g2−9g+4
Step-by-step explanation: 3g2+−g+3g2+−8g+4
=(3g2+3g2)+(−g+−8g)+(4)
=6g2+−9g+4
For this case we have:
Diana:
mile in 5 minutes.
To find the speed we divide the distance by the time:
Thus, Diana's speed is
Fernando:
mile in
Thus, Fernando's speed is
We find the speed in miles per hour considering that an hour has 60 minutes.
Diana:
Fernando:
Answer:
Diana's speed is
Fernando's speed is
Answer:
Your answer is -14k - 14 or k = -1
Step-by-step explanation:
-17k - 35 + 3k + 21 ( Combine like terms )
-14k - 14
-14k = 14
k = -1
Hope this helps!
