<h2>395,980</h2><h3 /><h3>3 = 300,000</h3><h3>9 = 90,000</h3><h3>5 = 5,000</h3><h3>9 = 900</h3><h3>8 = 80</h3><h3>0 = 0</h3><h3 /><h2 />
Get the LCM of 6 and 15 which is 30
Now you have to get each denominator to 30

This is x when
. So

Then


And


So
The rocket travels 200 meters horizontally.
b How high does the rocket reach mid-flight?
This it the height y when x = 0, so:

The height of the rocket mid-flight is of 1000 meters.
They are right except for 12. i think it is C but i could be wrong.
