Step-by-step explanation:
Since they have a common denominator the answer is (-5 + 2) / 6 = -3 / 6 = -1/2.
1 yard= 3 feet
4*3=12 (we do this to find how long the floor is)
10*12=120 (this is in feet, but it needs to be converted to yards)
120/3=40
You need 40 yards of tile

Assuming I see a force F acting on an object at an angle theta with the horizontal pushing it through a rough surface over a distance L such that the horizontal component is just required to overcome friction.
Then work done is
W=FLcos(theta)
(Read assumptions above due to lack of diagram)
