Answer:
x=10
Step-by-step explanation:
(7x - 23)° + (11x + 23)° = 180°
7x - 23° + 11x + 23° = 180°
18x = 180° / : 18
x = 10°
5c^5 + 60c^4 + 180c^3
find the GCF, 5c³
5c³(5c^5 + 60c^4 + 180c^3/ 5c^3)
5c³(c² + 12c + 36)
5c³(c² + 2(c)(6) + 6²)
5c³(c + 6)² <<< the answer.
hope this helps, God bless!
(1500 meters) / (about 3.5 minutes) =
(1500/about 3.5) (meters/minute) =
<em>about 428.6 meters/minute</em>
