Answer:
2x+5
Step-by-step explanation:
Formula for the perimeter of a reactangle= 2(l+b)
So,
2(l+b) = 10x+18
2(3x+4 + b) = 10x+18
Rearrange and solve
3x+4+b = 5x+9
b = 5x+9 - 3x - 4
b = 2x+5
Thus the measurement of the width = 2x+5
Hope this helps
These 'l l' lines mean absolute value. essentially it's asking how many units away from 0 a number is. Because of this all absolute values are positive numbers
l-18l=18
