Set sin x to a variable, i.e. u
u^2-u-2/u-2.
Factor:
(u-2)(u+1)/(u-2)
Simplify by canceling the u-2s...
leaving u+1. Since we substituted u for sin x...
the answer is A. sin x + 1
Answer:
Step-by-step explanation:
1). Geometric mean of a and b = ![\sqrt{a\times b}](https://tex.z-dn.net/?f=%5Csqrt%7Ba%5Ctimes%20b%7D)
Therefore, geometric mean of 2 and 50 = ![\sqrt{2\times 50}](https://tex.z-dn.net/?f=%5Csqrt%7B2%5Ctimes%2050%7D)
= 10
2). By geometric mean theorem,
![\frac{JM}{KM}=\frac{KM}{ML}](https://tex.z-dn.net/?f=%5Cfrac%7BJM%7D%7BKM%7D%3D%5Cfrac%7BKM%7D%7BML%7D)
![\frac{6}{e}=\frac{e}{24}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7Be%7D%3D%5Cfrac%7Be%7D%7B24%7D)
e² = 6 × 24
e = √144
e = 12
Similarly, ![\frac{JL}{KJ}=\frac{KJ}{JM}](https://tex.z-dn.net/?f=%5Cfrac%7BJL%7D%7BKJ%7D%3D%5Cfrac%7BKJ%7D%7BJM%7D)
![\frac{6+24}{d}=\frac{d}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B6%2B24%7D%7Bd%7D%3D%5Cfrac%7Bd%7D%7B6%7D)
d² = 6 × 30
d = √180
d = 6√5
And ![\frac{JL}{KL}=\frac{KL}{ML}](https://tex.z-dn.net/?f=%5Cfrac%7BJL%7D%7BKL%7D%3D%5Cfrac%7BKL%7D%7BML%7D)
![\frac{6+24}{c}=\frac{c}{24}](https://tex.z-dn.net/?f=%5Cfrac%7B6%2B24%7D%7Bc%7D%3D%5Cfrac%7Bc%7D%7B24%7D)
c² = 30 × 24
c = √720
c = 12√5
