Determine whether each statement "makes sense" or "does not make sense" and explain your reasoning. I made a mistake when I used \(x\) and \(x+2\) to represent two consecutive odd integers, because 2 is even.
Divide and simplify: \(\frac{-7 y}{-7}\).
A rectangular field is four times as long as it is wide. If the perimeter of the field is 500 yards, what are the field's dimensions?
Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. If the length of a rectangle is 6 inches more than its width, and its perimeter is 24 inches, the distributive property must be used to solve the equation that determines the length.
