1. Perform the addition:
(5x + 7) + (x - 2)
2. The length of a rectangular wall is x units and its height is (x - 3) units. Find an expression for the perimeter of the wall.
3. A rectangular garden has a length (t + 5) feet and width 2t feet. Find an expression for the perimeter of the garden.
4. Find the difference:
(t - 5) - (3t - 1)
Please do not bash me, tell me I need to do my own homework etc. Out of a 50 question exam, this is what I am left with. They may be simple to you, but not to me at the moment. I have just suffered a death in the family, I come here for answers and not to be told this or that etc.
Thanks in Advance to anyone who helps. :)
