Question

A non-zero whole number is represented by x. Select the statement that is true about x and -x.

A. Their difference is zero.
B. Their quotient is zero.
C. Their product is zero.
D. Their sum is zero.

Answer 1

The sum of x and -x is always zero.

Step-by-step explanation:

The statement that is true about x and -x is D. Their sum is zero.

When a non-zero whole number is represented by x, the opposite of x, which is -x, can be obtained. When you add x and -x together, the result is always zero. For example, if x is 3, then -x is -3, and 3+(-3) equals zero.
