Expanding the given expressions using Foil:
1)(–7x + 4)(–7x + 4) =
2) (–7x + 4)(4 – 7x)=
3)(–7x + 4)(–7x – 4)=
=
4)(–7x + 4)(7x – 4)=
The third option that is (–7x + 4)(–7x – 4) is difference of two squares.
Answer:

You will get 11.75 inches per side.
However, since they want you to round to the near tenth, the answer will actually be 11.8 inches.
Answer
Since sin x= cos (90- x)
Sin40=cos(90-40)
Sin 40=cos 50
X=50
