x = 
Step-by-step explanation:
Given
19 -
= 7 ( subtract 19 from both sides )
-
= - 12
Multiply both sides by - 4 to clear the fraction and the negative signs
5x + 6 = 48 ( subtract 6 from both sides )
5x = 42 ( divide both sides by 5 )
x = 
Power is work done per time and work done is force times distance. The power is found by multiplying the force(20N) and the distance(5m) and dividing the product by the time(5s)
(20*5)/5=20Nm/s OR 20 watts.
Therefore the power needed is 20 watts.
2 yards = 6 feet
6 times 5 is 30
30 ft squared
