1. What must be added to p to produce q?
2. What is the perimeter of the rectangle if the length is 2x-3y and the width is x+2y? What is the area?
3. What must be subtracted to 7y to leave -5y+2z?

1. q = 1 - p

2. Perimeter of rectangle = 2 length + 2 width. Area is length times width. Substitute the appropriate x and y terms.

3.When taking away somthing, you subtract "from" rather than subtract "to."

7y - (12y-2z) = -5y+2z

I hope this helps. Thanks for asking.
