I might not understand this correctly because of the misspellings, but if you draw a right angle. There is only 1 right angle... in a right angle.
Answer:
By using the energy conservation law, the input energy must be equivalent to the output energy. If you measured output energy is lower than your input energy, you have lost that difference of energy either in mechanical inefficiency (friction, heat, etc.) or an energy sink.
Thus, the energy not output by the machine is lost in the process within the machine.

To match the number with the opposite, we are flipping the sign. If the sign is originally a negative, it would become a positive, and vice versa.
Term: 3.2 Match (Opposite): B) - 3.2

Answer
75r^4 t^2 + 25r^4 t^6
The answer is -1/5. If you use slope intercept formula of (-7,2) and (-2,1) you get -1/5
