Afternoon.
I need help on an algebra question. The question is as follows:
‘Write an expression for the perimeter of this rectangle. Then simplify your answer.
When you multiply out the brackets, you will have:’
The answers are:
1. 8x + 12
2. 3×2 + 6x + 5
3. 3×2 + 5x + 6
4. 4x + 6
The rectangle has 2 sides labelled. One is 3x+1, the other is x+5
Can anyone please help me with how to get the answer? I have tried 3 different methods and have not come up with an answer in the list given.
Thank you.
