Explanation opens after your attempt
A. (3x+9)
Concept
Adding like terms gives (2x+x=3x) and (5+4=9). Therefore the sum is (3x+9).
Why this answer is correct
The correct answer is A. (3x+9). Adding like terms gives (2x+x=3x) and (5+4=9). Therefore the sum is (3x+9).
Exam Tip
समान पद जोड़ने पर (2x+x=3x) और (5+4=9) मिलता है। इसलिए योग (3x+9) है।
