Final answer:
The compound sentence constructed from the two simple sentences is 'I need my sunglasses, and my brother needs his beach ball.' By using the coordinating conjunction 'and', we combine the two independent clauses into one compound sentence.
Step-by-step explanation:
To create a compound sentence from two simple sentences, you can use a coordinating conjunction such as 'and'. In this case, the two simple sentences provided are 'I need my sunglasses.' and 'My brother needs his beach ball.'
A compound sentence that combines these could be: 'I need my sunglasses, and my brother needs his beach ball.'
In this compound sentence, there are two independent clauses each having their own subject and verb which are connected by the conjunction 'and' to form a single, cohesive sentence.
A compound sentence can be created by using a coordinating conjunction to join two simple sentences. In this case, we can use the coordinating conjunction 'and' to join the two simple sentences 'I need my sunglasses' and 'My brother needs his beach ball'.
The compound sentence would be: 'I need my sunglasses, and my brother needs his beach ball.'
This compound sentence combines two independent clauses and maintains the meaning of the original sentences.
