Answer: <em>4x+2</em>
Step-by-step explanation:
<em>Let's take our equation to start</em>
<em>2(3x+5)-2(x+4)</em>
<em>Distribute the 2 and -2 into the parenthesis</em>
<em>6x+10-2x-8</em>
<em>Now combine the like terms</em>
<em>6x-2x=4x</em>
<em>10-8=2</em>
<em>4x+2</em>
Let x be the speed of the first car in miles per hour. After 12 hours it will have gone 12x miles. The other car, driving east, has speed x+ 4. After 12 hours it will have gone 12(x+ 4) miles. Again by the Pythagorean theorem,
(12x)^2+(12(x+4)^2=600^2. Solve that equation for x.
