</span><span>2x(x) - 2x(5) + 3(x) - 3(5) (applying distributive property)
</span><span>2x^2 - 10x + 3x - 15 (simplifying)
</span><span>2x^2 - 7x - 15 (combining like terms)
I found this as an example from research. I do hope this helps. I have trouble in the same subject or I used to anyway. I hope this is what you were looking for. :)</span></span>

Answer:
The speed of the cars is 
Step-by-step explanation:
First we must first have the clear concept that
or 
Our question is the speed of the cars then the variable to clear will be s.
Let's raise the equation for each car taking into account that we have the following data:
Car 1:
,
and 
Car 1:
,
and 
The two cars travel the same distance so we will raise the distance formula for each car and then match them.
<em>Car 1</em>



<em>Car 2</em>







The speed of the cars is 32 km/hr
