The sentence is a compound-complex sentence.
The sentence provided is a compound-complex sentence because it is made up of two independent clauses and one dependent clause. An independent clause is a clause that can stand alone as a sentence. In contrast, a dependent clause does not express a complete thought; therefore, it cannot stand on its own. The two independent clauses in this sentence are "You tell him" and "try to undo the damage", while the dependent clause is "I'll take over from here", which is a that-clause and also a noun clause. The dependent clause has been joined to the independent clause "try to undo the damage" by means of the coordinating conjunction "and".
