15) factor out cos: cos(x)(sin(x)+1)=0
Now this is true when either cos(x)=0 (x=pi/2 and 3pi/2)
Or when sin(x)=-1 (x=3pi/2)
So it's solutions are pi/2 and 3pi/2
Answer:

Answer:
The value of y is 12
Step-by-step explanation:
y∝x

Answer:
−9d+13
Step-by-step explanation:
3d+4−(6d−9)
Distribute the Negative Sign:
=−3d+4+−1(6d−9)
=−3d+4+−1(6d)+(−1)(−9)
=−3d+4+−6d+9
Combine Like Terms:
=−3d+4+−6d+9
=(−3d+−6d)+(4+9)
=−9d+13
Answer:
=−9d+13
