यदि (B(x)=140-8x), तो (B(x-2)-B(x+3)) का मान क्या है?
If (B(x)=140-8x), what is the value of (B(x-2)-B(x+3))?
Explanation opens after your attempt
C. (40)
Concept
Over ((x+3)-(x-2)=5) steps, the value decreases by \(8\times5=40\). So the difference is (40).
Why this answer is correct
The correct answer is C. (40). Over ((x+3)-(x-2)=5) steps, the value decreases by \(8\times5=40\). So the difference is (40).
Exam Tip
((x+3)-(x-2)=5) चरणों में मान \(8\times5=40\) घटता है। इसलिए अंतर (40) है।
