Find the area of the region bounded by the lines \(y = 2x + 3\) and \(y = x + 7\) and the vertical line \(x = 0\). In your answer, determine the intersection point of the two lines, set up the definite integral representing the area between the curves over the appropriate interval, and evaluate the integral.

Hint Hint

Hint

Start by finding the x-coordinate where \(2x+3 = x+7\) to determine the intersection, then identify the upper and lower functions between \(x=0\) and this intersection.
