3x^2 = 48
x^2 = 48/3
x^2 = 16
x =
x = 4
B. x^2 - 121 = 0
x^2 = 121
x =
x = 11
C. (b + 4 )2 = 49

Answer:
Amount of input horsepower needed is 279.3 hp.
Step-by-step explanation:
if there is a loss of power of 5% the base horsepower will need to be increased by same percentage so that same amount of power can be delivered.
Now to calculate 5% of 266 hp, we can write
266 × = 13.3 hp
Now to deliver same amount of power we will have to add 5% of 266 hp to its actual power.
So real base power which is needed to deliver 266hp output even at a loss of 5% will be = (266+13.3) hp = 279.3 hp
