6n - 10 = 4n + 6
6n - 10 + 10 = 4n + 6 + 10
6n = 4n + 16
6n -4n = 4n - 4n + 16
2n = 16
2n/2 = 16/2
n = 8.
The solution is that the value of n = 8.
Answer:
B)
Step-by-step explanation:
If you try to divide 135 with each number,every number is divisible by 135 XD
<span>cos(x)/(1+sin(x) )+(1+sin(x))/cos(x) =2sec(x)
Work on the left hand side.
</span>[Common denominator is (1+sin(x))*cos(x)]
cos(x)/(1+sin(x) )+(1+sin(x))/cos(x) <span>
= (cos(x)^2+(1+sin(x))^2)/(</span>(1+sin(x))*cos(x))
=(cos(x)^2+1+sin(x)^2+2sin(x))/((1+sin(x))*cos(x))
=(cos(x)^2+sin(x)^2+1+2sin(x))/((1+sin(x))*cos(x))
=(1+1+2sin(x))/((1+sin(x))*cos(x))
=(2+2sin(x))/((1+sin(x))*cos(x))
=2(1+sin(x))/((1+sin(x))*cos(x))
=2/cos(x)
=2 sec(x) [QED]
