4/6 = 14/21
When using cross product always multiply the left fractions numerator times the right side fractions denominator and the left side fractions denominator times the right side fractions numerator
4×21 = 6×14
84=84
They are equivalent because they both equal 84
Answer:
3x
Step-by-step explanation:
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
Or...you could do this.
