Answer:
13. 360 14. 1080 15. x=53 16. x=135
Step-by-step explanation:
Equation: (n-2)*180
For 13. all angles in a a quadrilateral add up to 360
For 14. 8 sides-2=6. 180*6=1080 degrees
For 15. 15+155+137=307. 360-307=53. x=53 degrees
For 16. 6 sides-2=4. 4*180=720. 90*2=180. 720-180=540. 540/4=135.
x=135
C. Is the answer to your question
Answer:
L = 50 * (-0.4)^(n - 1)
Step-by-step explanation:
r = t2/t1 = -20/50 = - 0.4
a = 50
L = 50 * (r)^(n - 1) Let's see if we can get the answer when n = 3
L=50 * (-0.4)^(3 -1)
L =50* (-0.4)^2
L = 50 * 0.16
L = 8 which is correct
x^(2)y (6y^(2)-3y+5)
Find the prime factors of each term in order to find the greatest common factor (GCF).
Brainliest or a thank you please! sorry im wrong :(
