First you would subtract x from both sides to move all the x's to one side
Then you would add 4 to both side to move all the non x's to one side
Lastly divide by negative 15 to have x by itself
9/-15 =-.6
So x as has root at x=-0.6
Answer: 0.15 m
Step-by-step explanation:
Using the small angle formula
D= kd/206265 where
k= 22 and d= 1400
D= 22 x 1400/206265
D=0.149 m
Hence the linear diameter is 0.15 m.
