Which of the following represents, the difference of a number squared and four is less than or equal to five.


  1. Answer:
    x² – (4 ≤ 5)
    Step-by-step explanation:
    (I have x representing the number that is squared, it might be a different letter on your options, but regardless it will be the same general answer. You also may not need the parentheses around the 4 ≤ 5)
    Difference means subtraction so we know that the second number/group of numbers will be subtracted from the first that is listed.
    Next, if you are squaring any number it’s going to have the little 2 to the right of it. That’s what that means.
    Then, we look at that last bit. “Four is less than or equal to five.” This means exactly how it sounds. To write this we need the symbol ≤. This symbol means less than or equal to. You would would but the 4 in front and the 5 in back to get 4 ≤ 5.
    Now we just put it together. It tells us that 4 ≤ 5 is being subtracted from a number squared. So this means that a number squared needs to be first, and because difference means subtraction, we would subtract 4 ≤ 5 from that. A number squared can be represented by any letter variable, but for this example, I will use x.
    This leaves you with x² – (4 ≤ 5)
    I hope this helped 🙂
