Patrice cuts a piece of board 4 feet long from a board that is x feet long. Find an expression that describes the length in feet of the original after the cut.

a. 4 + x
b. 4x
c. 4 - x
d. x - 4
I pick d, is that the correct answer?

Right.

H-Hey...

Lmao this is what I'm doing with my life now

No, the correct answer is a.

After cutting a piece of board that is 4 feet long from a board that is x feet long, the length of the original board can be expressed as x - 4 feet, not x - 4.

Hence, the correct expression that describes the length in feet of the original board after the cut is 4 + x.

To determine the correct answer, let's analyze the situation. Patrice cuts a piece of board that is 4 feet long from a board that is x feet long. After the cut, what remains of the original board will be equal to the original length minus the length of the cut piece.

Therefore, the correct expression that describes the length in feet of the original board after the cut is:

Original length - Length of the cut piece

In this case, the original length is x feet and the length of the cut piece is 4 feet. Hence, the correct expression is:

x - 4

So, your choice of option d, "x - 4", is indeed the correct answer.
