Rearrange Integrate
1. The problem asks to rearrange the expression $2 + \sqrt{x+4}$ in the form $y = ...$ before integrating.
2. We start by defining the function:
$$y = 2 + \sqrt{x+4}$$
3. This expresses $y$ explicitly in terms of $x$, which is suitable for integration.
4. To integrate, you would compute:
$$\int y \, dx = \int \left(2 + \sqrt{x+4}\right) dx$$
5. Break the integral into parts:
$$\int 2 \, dx + \int \sqrt{x+4} \, dx = 2x + \int (x+4)^{1/2} \, dx$$
6. Use a substitution for the second integral, let $u = x+4$, so $du = dx$:
$$\int u^{1/2} \, du = \frac{2}{3} u^{3/2} + C = \frac{2}{3} (x+4)^{3/2} + C$$
7. Therefore, the integral is:
$$2x + \frac{2}{3} (x+4)^{3/2} + C$$
8. Final answer:
$$\int \left(2 + \sqrt{x+4}\right) dx = 2x + \frac{2}{3} (x+4)^{3/2} + C$$
