Answer:
Complex Sentence
Declarative Sentence
Explanation:
The sentence is declarative because it makes a statement, instead of asking a question (Interrogative Sentence), making a command (Imperative Sentence), or communicating a strong emotion (Exclamatory Sentence).
It´s also a complex sentence, not a simple, compound nor Compound-Complex Sentence because it has one independent clause (Steve paced impatiently) and one dependent clause (Hoping his mother would arrive soon).
