Alrighty, so you said, simplify: 4t (2s - 7)

When there is a variable or number outside of the parenthesis, it means that it wants the whole thing multiplied by that number.

So, your right way to do this is:

4t (2s) + 4t (-7)

Simplify.

8st - 28t

So, the student incorrectly simplified them because she didn't multiply -7 by 4t like they should have.

~Hope I helped!~

Well what you need to do is find the perimeter of both rectangles.
Rectangle A: ((2x+8)*2)+((x-1)*2)
Rectangle B: ((3x + 5)*2)+((2x-2)*2)
That will be (10x+6)-(6x+14)=4x-8
Your answer will be D.
Hope this is useful
