Question 241693: I am not sure if I set it up correctly please help me by correcting me, or if I am right please tell me what to do afterwards because I am stuck, thank you.
Write and simplify expressions for (A) the perimeter (B) the area
It's a rectangle:
One side is 2x-3
The other side is 5x
So far I have this:
Perimeter:
2L+2W
2(2x-3)+2(5x)
4x-6+10x
I don't know what to do next

Area:
A=LW
5x(2x-3)
10x^2-15x
Here I am also at a loss, I am not sure what to do.
Please help me and correct me.
Thank you.

There is just one more step, and that is to
combine the first term 4x with the last term
+10x and get +14x, so the final answer is
simply:

14x-6

Area:
A=LW
5x(2x-3)
10x^2-15x
Here I am also at a loss, I am not sure what to do.
Please help me and correct me.



You have finished that one already and it is correct.

Thank you.


You're welcome!
