Sure! To solve the integral ∫(2x + 3) dx, you can use the power rule for integration. First, distribute the integral to get ∫2x dx + ∫3 dx. Then, use the power rule to integrate each term separately. The integral of 2x with respect to x is x^2, and the integral of 3 with respect to x is 3x. So the final result is x^2 + 3x + C, where C is the constant of integration. **

The elongation step between 3 and 4 mm is 1 mm. This means that the distance between the two points increases by 1 mm.
