(5x²+3)+(15x²+2)
5x^2+15x^2+3+2
20x^2+5
5(4x^2+1)

(14h^4+3h^3)-(9h^4+2h^3)
14h^4-9h^4+3h^3-2h^3
5h^4+h^3
h^3(5h+1)
Calculate total distance
distance = speed * time
= 480 * 9
=4320MILES
therefore trip to Las Vegas
time = distance/ speed
=4320/ 432
= 10hours
-4x^5 + 2x^4 + x^3 + 3x^2 + 9x
Hope this helps!
