The answer is x=-6
2+(-3x)+(-7)=-x+19
-3x+-5=-x+19
-3x=x+24
-4x=24
x=-6
If possible is to impossible then <u>certain</u> is to uncertain..
Answer:
<em>For distance of 9 meters, work done is 360 Nm and for three times of that distance, work done is 1080 Nm.</em>
Step-by-step explanation:
<u>Formula for work done</u> is:
, where
Force and
Distance.
Now a force of 40 newtons moves a cart a distance of 9 meters. That means here,
and 
So, the work done will be:
Nm.
If the same force moves the same cart three times that distance, then
and 
So, the work done will be:
Nm.
