यदि (B(x)=180-5x), तो (B(x-3)-B(x+4)) का मान क्या है?
If (B(x)=180-5x), what is the value of (B(x-3)-B(x+4))?
Explanation opens after your attempt
C. (35)
Concept
Over ((x+4)-(x-3)=7) steps the value decreases by \(5\times7=35\). So the difference is (35).
Why this answer is correct
The correct answer is C. (35). Over ((x+4)-(x-3)=7) steps the value decreases by \(5\times7=35\). So the difference is (35).
Exam Tip
((x+4)-(x-3)=7) चरणों में मान \(5\times7=35\) घटता है। इसलिए अंतर (35) है।
