Answer:
(9 -5x) + (-9 +5x)
Step-by-step explanation:
-Three times two is six plus three is nine
-Negative three times two is negative six minus three which is negative nine

Answer:
The perimeter =72
The width = 16
The length = 20
Step-by-step explanation:
.A rectangle has 4 sides , so 72 divided by four is 18. The question is that the width is 4 less than the length. The difference between the length and the width is 4 so increase the length by 2 and decrease the width by 2. Now the numbers obtained are 16 ( 18 decreased by 2) and 20 (18 increased by 2). It is mentioned in the question that the width is less and length is more.
