7 0

Solution

for this case we can do the following multiplicating the two terms

7x(5x^2)+7x(9x)+7x(6)+4(5x^2)+4(9x)+4(6)

If we multiply we got:

35x^3+63x^2+42x+20x^2+36x+24

And if we simplify we got:

35x^3+73x^2+78x+24

x 5x^2 9x 6

7x 35x^2 63x^2 42x

4 20x^2 36x 24

A car that travels 20 miles in 1/2 hour at constant speed is traveling at the same speed as a car that travels 30 miles in 3/4 h
Vsevolod [243]
It’s because 2/3 of 30 miles in 3/4 hours is the same as 20 miles in 1/2 hour.

Proof:

30/1x2/3
60/3 = 20

3/4x2/3
6/12 = 1/2
