यदि (B(x)=260-9x), तो (B(x-4)-B(x+3)) का मान क्या है?
If (B(x)=260-9x), what is the value of (B(x-4)-B(x+3))?
Explanation opens after your attempt
B. (63)
Concept
Over ((x+3)-(x-4)=7) steps the value decreases by \(9\times7=63\). So the difference is (63).
Why this answer is correct
The correct answer is B. (63). Over ((x+3)-(x-4)=7) steps the value decreases by \(9\times7=63\). So the difference is (63).
Exam Tip
((x+3)-(x-4)=7) चरणों में मान \(9\times7=63\) घटता है। इसलिए अंतर (63) है।
