No es sagrado, ha perdido su valor al paso de los siglos y las personas no lo concideran un puente sagrado.
Answer:
I believe the answer is the first one, clases-llenas.
Explanation:
Clases is a feminine word (las clases, la clase), so it only makes sense for the adjective after it to be feminine as well (llenas). Please let me know if you still need help with this, and only mark as brainliest if you want!
Answer:
S7=49
7/2(2a+6d)=49
2a+6d=49×2/7
2a+6d=14
2a=14-6d
a=7-3d........1
S17=289
17/2×(2a+16d)=289
2a+16d=289×2/17
2a+16d=34
a+8d=17
substituting value of a
7-3d+8d=17
5d=17-7
d=10/5=2
substituting value of d in equation 1
a=7-3×2=1
<h3>
now</h3>
S20=20/2(2a+19d)=10(2×1+19×2)=10(40)
=40×10=400
Es prácticamente lo mismo no creo que haya diferencia
