To what ring is $\mathbb{Z}[X,Y,Z]/(X-Y, X^3-Z)$ isomorphic?

Are all finite-dimensional algebras of a fixed dimension over a field isomorphic to one another?

Showing that $\frac{\mathbb{R}[x]}{\langle x \rangle}$ and $\frac{\mathbb{R}[x]}{\langle x-1 \rangle}$ are not isomorphic as $\mathbb{R}[x]$ modules.

Is $\mathbb{Z}[x]/(x^2+2x+1)$ isomorphic to a product of non-trivial rings?

Example of an integral domain which is not a field
