Equivalent expressions are:
6x-3(3x-3)
-3(x-3)
-6x+3(3+3x)-6x
Step-by-step explanation:
We have to simplify each expression for comparison
Expression 1:
Expression 2:
Expression 3:
Expression 4:
Hence,
Equivalent expressions are:
6x-3(3x-3)
-3(x-3)
-6x+3(3+3x)-6x

Width of the reactangle = 38 cm
Minimum perimeter = 692 cm
Let the length of the rectangle be x cm
We know that,
Perimeter of rectangle = 2 * (length + width)
Since the perimeter should be atleast 692 cm. Therefore,
2 * (x + 38) > 692
2x + 76 > 692
2x > 692 - 76
2x > 616
x >
x > 308
Hence, the length of the rectangle should be more that 308 cms.
