Hi there! The first answer is correct.
Let's solve this equation step by step!
First add 4 to both sides of the equation
Now divide both sides of the equation by c. Because c is a negative number, we mustn't forget to flip te sign.
The first answer is correct.
~ Hope this helps you!

Answer:
n= -3 and n= -6
Step-by-step explanation:
We need to solve this equation to find the value of n.
Rearranging:
This is a quadratic equation and we can solve by using factorization method.
We need to make factors of 18n^2 such that their sum is equal to 9n.
So solving,
To solve the the question we proceed as follows:
From trigonometric laws
(cos x)^2+(sin x)^2=1
(cos y)^2+(sin y)^2=1
sin (x-y)=sin x sin y-sin y cos x
cos (x-y)=cos x cos y+ sin x sin y
si x=8/17
cos x=sqrt(1-(sin x)^2)=sqrt(1-64/289)=sqrt(225/289)=15/17
cos y=3/5
sin x= sqrt(1- (cos x)^2)= sqrt(1-9/25)=sqrt(16/25)=4/5
thus
tan (x-y)=[sin (x-y)]/[cos (x-y)]
=[sin x cos y-sin y cos x]/[cos x cos y+sin x sin y]
plugging in the values we obtain:
[8/17 *3/5-4/5*15/7]/[15/17*3/5+8/17*4/5]
simplifying
[24/85-60/85]/[45/85+32/85]
=-36/77
Answer:
i would say 1 because the numbers are going down at a constant while 2 is jumping down.
Hope this helps.
