Final answer:
The expression 0 - 53x - 21 can be simplified to -53x + 32.
Step-by-step explanation:
The expression 0 - 53x - 21 can be simplified by combining like terms. The coefficient of x is -53, so the first step is to distribute the -53 to both terms in the expression. This gives us 0 - 53x + 53(1). Simplifying further, we get 0 - 53x + 53. Since 53(1) is equal to 53, the expression becomes -53x + 53 - 21. Finally, combining like terms, we have -53x + 32.
Therefore, none of the expressions A, B, C, or D are equivalent to 0 - 53x - 21.
