So your equation would be x+3 times x+2 = 30
When you factor this out, you get x^2 + 5x + 6 = 30
Then you have to move the 30 over so you can set it equal to zero, so subtract 30 from both sides of the equal sign. 
You now have X^2 + 5x -24 =0
Here you'd try to refactor, but unfortunately that doesn't work in this equation so you have to use the quadratic formula. 

Look up the formula if you don't know it, it would be more confusing if I tried to type it out. Just keep in mind that for this equation, a=1 b=5 and c= -24.

Answer:

Kaylee drove her scooter for 2h and Sophia drove her scooter for 3h.

Step-by-step explanation:

From the graph shown below, we can see that the intersection point is (2,3). When using the graphing method to solve a system of equations, the intersection point is the answer. In this case, x = 2 and y = 3.
