A boat is travelling at a velocity represented by 2x3 - 10x2 + 7. At the same time, current is pushing the boat in the same direction with a velocity given by 5x3 + 19x2 + 4x. What is the total travelling velocity of the boat?

Respuesta :

Ok, 10x2-2x3=21.   21+4x+19x2+5x3= 79 . So the total traveling velocity is 79.
