Answer:
Option D: -3x + 5
Step-by-step explanation:
Here Given,
- x = White rectangular box
- -x = Black rectangular box
- 1 = White square
- -1 = Black square
Condition,
No. of White rectangular boxes = 5
- (On putting the value x) = 5x
No. of Black rectangular boxes = 8
- (On putting the value -x) = -8x
No. of White square boxes = 9
- (On putting the value 1) = 9
No. of Black square boxes = 4
- (On putting the value -1) = -4
Therefore Simplification,
5x + (-8x) + 9 + (-4)
= - 3x + 5 (Ans) (option D)
